Version 0.5.0-rc.1 (Jun 09, 2021)

Major Features and Improvements

This release introduces the following major features and improvements:

Support for Rust Stable

As a result of support for the stable release channel, the #![feature(..)] crate attribute is no longer required for Rocket applications. The complete canonical example with a single hello route becomes:

#[macro_use] extern crate rocket;

#[get("/<name>/<age>")]
fn hello(name: &str, age: u8) -> String {
    format!("Hello, {} year old named {}!", age, name)
}

#[launch]
fn rocket() -> _ {
    rocket::build().mount("/hello", routes![hello])
}
See a diff of the changes from v0.4. 
- #![feature(proc_macro_hygiene, decl_macro)]
-
 #[macro_use] extern crate rocket;

 #[get("/<name>/<age>")]
- fn hello(name: String, age: u8) -> String {
+ fn hello(name: &str, age: u8) -> String {
     format!("Hello, {} year old named {}!", age, name)
}

- fn main() {
-     rocket::ignite().mount("/hello", routes![hello]).launch();
- }
+ #[launch]
+ fn rocket() -> _ {
+     rocket::build().mount("/hello", routes![hello])
+ }

Breaking Changes

This release includes many breaking changes. The most significant changes are listed below.

Silent Changes

These changes are invisible to the compiler and will not yield errors or warnings at compile-time. We strongly advise all application authors to review this list carefully.

  • Blocking I/O (long running compute, synchronous sleep(), Mutex, RwLock, etc.) may prevent the server from making progress and should be avoided, replaced with an async variant, or performed in a worker thread. This is a consequence of Rust's cooperative async multitasking. For details, see the new multitasking section of the guide.
  • ROCKET_ENV is now ROCKET_PROFILE. A warning is emitted a launch time if the former is set.
  • The default profile for debug builds is now debug, not dev.
  • The default profile for release builds is now release, not prod.
  • ROCKET_LOG is now ROCKET_LOG_LEVEL. A warning is emitted a launch time if the former is set.
  • It is a launch-time error if secrets is enabled in non-debug profiles without a configured secret_key.
  • A misconfigured template_dir is reported as an error at launch time.
  • FileServer::new() fails immediately if the provided directory does not exist.
  • Catcher collisions result in a launch failure as opposed to a warning.
  • Default ranks now range from -12 to -1. There is no breaking change if only code generated routes are used. Manually configured routes with negative ranks may collide or be considered in a different order than before.
  • The order of execution of path and query guards relative to each other is now unspecified.
  • URIs beginning with : are properly recognized as invalid and rejected.
  • URI normalization now normalizes the query part as well.
  • The Segments iterator now returns percent-decoded &strs.
  • Forms are now parsed leniently by the Form guard. Use Strict for the previous behavior.
  • The Option<T> form guard defaults to None instead of the default value for T.
  • When data limits are exceeded, a 413 Payload Too Large status is returned to the client.
  • The default catcher now returns JSON when the client indicates preference via the Accept header.
  • Empty boolean form values parse as true: the query string ?f is the same as ?f=true.
  • Created<R> does not automatically send an ETag header if R: Hash. Use Created::tagged_body instead.
  • FileServer now forwards when a file is not found instead of failing with 404 Not Found.
  • Shield is enabled by default. You may need to disable or change policies if your application depends on typically insecure browser features or if you wish to opt-in to different policies than the defaults.
  • CookieJar get()s do not return cookies added during request handling. See CookieJar#pending.

General

  • Rocket is now generic over a phase marker:
    • APIs operate on Rocket<Build>, Rocket<Ignite>, Rocket<Orbit>, or Rocket<P: Phase> as needed.
    • The phase marker statically enforces state transitions in Build, Ignite, Orbit order.
    • rocket::ignite() is now rocket::build(), returns a Rocket<Build>.
    • Rocket::ignite() transitions to the Ignite phase. This is run automatically on launch as needed.
    • Ignition finalizes configuration, runs ignite fairings, and verifies sentinels.
    • Rocket::launch() transitions into the Orbit phase and starts the server.
    • Methods like Request::rocket() that refer to a live Rocket instance return an &Rocket<Orbit>.
  • Fairings have been reorganized and restructured for async:
    • Replaced attach fairings with ignite fairings. Unlike attach fairings, which ran immediately at the time of attachment, ignite fairings are run when transitioning into the Ignite phase.
    • Replaced launch fairings with liftoff fairings. liftoff fairings are always run, even in local clients, after the server begins listening and the concrete port is known.
  • Introduced a new configuration system based on Figment:
    • The concept of "environments" is replaced with "profiles".
    • ROCKET_ENV is superseded by ROCKET_PROFILE.
    • ROCKET_LOG is superseded by ROCKET_LOG_LEVEL.
    • Profile names can now be arbitrarily chosen. The dev, stage, and prod profiles carry no special meaning.
    • The debug and release profiles are the default profiles for the debug and release compilation profiles.
    • A new specially recognized default profile specifies defaults for all profiles.
    • The global profile has highest precedence, followed by the selected profile, followed by default.
    • Added support for limits specified in SI units: "1 MiB".
    • Renamed LoggingLevel to LogLevel.
    • Inlined error variants into the Error structure.
    • Changed the type of workers to usize from u16.
    • Changed accepted values for keep_alive: it is disabled with 0, not false or off.
    • Disabled the secrets feature (for private cookies) by default.
    • Removed APIs related to "extras". Typed values can be extracted from the configured Figment.
    • Removed ConfigBuilder: all fields of Config are public with constructors for each field type.
  • Many functions, traits, and trait bounds have been modified for async:
  • Functionality and features requiring Rust nightly were removed:
  • Rocket::register() now takes a base path to scope catchers under as its first argument.
  • ErrorKind::Collision has been renamed to ErrorKind::Collisions.

Routing and URIs

  • In #[route(GET, path = "...")], path is now uri: #[route(GET, uri = "...")].
  • Multi-segment paths (/<p..>) now match zero or more segments.
  • A route URI like (/<a>/<p..>) now collides with (/<a>), requires a rank to resolve.
  • All catcher related types and traits moved to rocket::catcher.
  • All route related types and traits moved to rocket::route.
  • URI formatting types and traits moved to rocket::http::uri::fmt.
  • T no longer converts to Option<T> or Result<T, _> for uri! query parameters.
  • For optional query parameters, uri! requires using a wrapped value or _.
  • &RawStr no longer implements FromParam: use &str instead.
  • Percent-decoding is performed before calling FromParam implementations.
  • RawStr::url_decode() and RawStr::url_decode_lossy() allocate as necessary, return Cow.
  • RawStr::from_str() was replaced with RawStr::new().
  • Origin::segments() was replaced with Origin.path().segments().
  • Origin::path() and Origin::query() return &RawStr instead of &str.
  • The type of Route::name is now Option<Cow<'static, str>>.
  • Route::set_uri was replaced with Route::map_base().
  • Route::uri() returns a new RouteUri type.
  • Route::base was removed in favor of Route.uri().base().

Data and Forms

  • Removed FromDataSimple. Use FromData and request::local_cache!.
  • Data now has a lifetime: Data<'r>.
  • Data::open() indelibly requires a data limit.
  • All DataStream APIs require limits and return Capped<T> types.
  • Form types and traits were moved from rocket::request to rocket::form.
  • Removed FromQuery. Dynamic query parameters (#[get("/?<param>")]) use FromForm instead.
  • Replaced FromFormValue with FromFormField. All T: FromFormField implement FromForm.
  • Form field values are percent-decoded before calling FromFormField implementations.
  • Renamed the #[form(field = ...)] attribute to #[field(name = ...)].

Request Guards

  • Renamed Cookies to CookieJar. Its methods take &self.
  • Renamed Flash.name to Flash.kind, Flash.msg to Flash.message.
  • Replaced Request::get_param() with Request::param().
  • Replaced Request::get_segments() to Request::segments().
  • Replaced Request::get_query_value() with Request::query_value().
  • Replaced Segments::into_path_buf() with Segments::to_path_buf().
  • Replaced Segments and QuerySegments with Segments<Path> and Segments<Query>.
  • Flash constructors to take Into<String> instead of AsRef<str>.
  • The State<'_, T> request guard is now &State<T>.
  • Removed a lifetime from FromRequest: FromRequest<'r>.
  • Removed a lifetime from FlashMessage: FlashMessage<'_>.
  • Removed all State reexports except rocket::State.

Responders

  • Moved NamedFile to rocket::fs::NamedFile
  • Replaced Content with content::Custom.
  • Response::body and Response::body_mut are now infallible methods.
  • Renamed ResponseBuilder to Builder.
  • Removed direct Response body reading methods. Use methods on r.body_mut() instead.
  • Removed inaccurate "chunked body" types and variants.
  • Removed Responder impl for Response. Prefer custom responders with #[derive(Responder)].
  • Removed the unused reason phrase from Status.

Contrib Graduation

  • The rocket_contrib crate has been deprecated and should no longer be used.
  • Several features previously in rocket_contrib were merged into rocket itself:
  • The remaining features from rocket_contrib are now provided by separate crates:
    • Replaced rocket_contrib::templates with rocket_dyn_templates.
    • Replaced rocket_contrib::databases with rocket_sync_db_pools.
    • These crates are versioned and released independently of rocket.
    • rocket_contrib::databases::DbError is now rocket_sync_db_pools::Error.
    • Removed redis, mongodb, and mysql integrations which have upstream async drivers.
    • The #[database] attribute generates an async run() method instead of Deref implementations.

Version 0.4.0 (Dec 06, 2018)

New Features

This release includes the following new features:

Codegen Rewrite

The rocket_codegen crate has been entirely rewritten using to-be-stable procedural macro APIs. We expect nightly breakages to drop dramatically, likely to zero, as a result. The new prelude import for Rocket applications is:

- #![feature(plugin)]
- #![plugin(rocket_codegen)]
+ #![feature(proc_macro_hygiene, decl_macro)]

- extern crate rocket;
+ #[macro_use] extern crate rocket;

The rocket_codegen crate should not be a direct dependency. Remove it from your Cargo.toml:

[dependencies]
- rocket = "0.3"
+ rocket = "0.4"
- rocket_codegen = "0.3"

Breaking Changes

This release includes many breaking changes. These changes are listed below along with a short note about how to handle the breaking change in existing applications when applicable.

  • Route and catcher attributes respect function privacy.

    To mount a route or register a catcher outside of the module it is declared, ensure that the handler function is marked pub or crate.

  • Query handling syntax has been completely revamped.

    A query parameter of <param> is now <param..>. Consider whether your application benefits from the revamped query string handling.

  • The #[error] attribute and errors! macro were removed.

    Use #[catch] and catchers! instead.

  • Rocket::catch() was renamed to Rocket::register().

    Change calls of the form .catch(errors![..]) to .register(catchers![..]).

  • The #[catch] attribute only accepts functions with 0 or 1 argument.

    Ensure the argument to the catcher, if any, is of type &Request.

  • json! returns a JsonValue, no longer needs wrapping.

    Change instances of Json(json!(..)) to json! and change the corresponding type to JsonValue.

  • All environments default to port 8000.

    Manually configure a port of 80 for the stage and production environments for the previous behavior.

  • Release builds default to the production environment.

    Manually set the environment to debug with ROCKET_ENV=debug for the previous behavior.

  • Form and LenientForm lost a lifetime parameter, get() method.

    Change a type of Form<'a, T<'a>> to Form<T> or Form<T<'a>>. Form<T> and LenientForm<T> now implement Deref<Target = T>, allowing for calls to .get() to be removed.

  • ring was updated to 0.13.

    Ensure all transitive dependencies to ring refer to version 0.13.

  • Uri was largely replaced by Origin.

    In general, replace the type Uri with Origin. The base and uri fields of Route are now of type Origin. The &Uri guard is now &Origin. Request::uri() now returns an Origin.

  • All items in rocket_contrib are namespaced behind modules.

    • Json is now json::Json
    • MsgPack is now msgpack::MsgPack
    • MsgPackError is now msgpack::Error
    • Template is now templates::Template
    • UUID is now uuid::Uuid
    • Value is replaced by json::JsonValue

  • TLS certificates require the subjectAltName extension.

    Ensure that your TLS certificates contain the subjectAltName extension with a value set to your domain.

  • Route paths, mount points, and LocalRequest URIs are strictly checked.

    Ensure your mount points are absolute paths with no parameters, ensure your route paths are absolute paths with proper parameter syntax, and ensure that paths passed to LocalRequest are valid.

  • Template::show() takes an &Rocket, doesn't accept a root.

    Use client.rocket() to get a reference to an instance of Rocket when testing. Use Template::render() in routes.

  • Request::remote() returns the actual remote IP, doesn't rewrite.

    Use Request::real_ip() or Request::client_ip() to retrieve the IP address from the "X-Real-IP" header if it is present.

  • Bind variant was added to LaunchErrorKind.

    Ensure matches on LaunchErrorKind include or ignore the Bind variant.

  • Cookies are automatically tracked and propagated by Client.

    For the previous behavior, construct a Client with Client::untracked().

  • UUID was renamed to Uuid.

    Use Uuid instead of UUID.

  • LocalRequest::cloned_dispatch() was removed.

    Chain calls to .clone().dispatch() for the previous behavior.

  • Redirect constructors take a generic type of T: TryInto<Uri<'static>>.

    A call to a Redirect constructor with a non-'static &str of the form Redirect::to(string) should become Redirect::to(string.to_string()), heap-allocating the string before being passed to the constructor.

  • The FromData impl for Form and LenientForm now return an error of type FormDataError.

    On non-I/O errors, the form string is stored in the variant as an &'f str.

  • Missing variant was added to ConfigError.

    Ensure matches on ConfigError include or ignore the Missing variant.

  • The FromData impl for Json now returns an error of type JsonError.

    The previous SerdeError is now the .1 member of the JsonError enum. Match and destruct the variant for the previous behavior.

  • FromData is now emulated by FromDataSimple.

    Change implementations, not uses, of FromData to FromDataSimple. Consider whether your implementation could benefit from transformations.

  • FormItems iterates over values of type FormItem.

    Map using .map(|item| item.key_value()) for the previous behavior.

  • LaunchErrorKind::Collision contains a vector of the colliding routes.

    Destruct using LaunchErrorKind::Collision(..) to ignore the vector.

  • Request::get_param() and Request::get_segments() are indexed by segment, not dynamic parameter.

    Modify the n argument in calls to these functions appropriately.

  • Method-based route attributes no longer accept a keyed path parameter.

    Change an attribute of the form #[get(path = "..")] to #[get("..")].

  • Json and MsgPack data guards no longer reject requests with an unexpected Content-Type

    To approximate the previous behavior, add a format = "json" route parameter when using Json or format = "msgpack" when using MsgPack.

  • Implemented Responder for Status. Removed Failure, status::NoContent, and status::Reset responders.

    Replace uses of Failure(status) with status directly. Replace status::NoContent with Status::NoContent. Replace status::Reset with Status::ResetContent.

  • Config::root() returns an Option<&Path> instead of an &Path.

    For the previous behavior, use config.root().unwrap().

  • Status::new() is no longer const.

    Construct a Status directly.

  • Config constructors return a Config instead of a Result<Config>.

  • ConfigError::BadCWD, Config.config_path were removed.

  • Json no longer has a default value for its type parameter.

  • Using data on a non-payload method route is a warning instead of error.

  • The raw_form_string method of Form and LenientForm was removed.

  • Various impossible Error associated types are now set to !.

  • All AdHoc constructors require a name as the first parameter.

  • The top-level Error type was removed.

General Improvements

In addition to new features, Rocket saw the following improvements:

  • Log messages now refer to routes by name.

Breaking Changes

This release includes many breaking changes. These changes are listed below along with a short note about how to handle the breaking change in existing applications.

  • session_key was renamed to secret_key, requires a 256-bit base64 key

    It's unlikely that session_key was previously used. If it was, rename session_key to secret_key. Generate a random 256-bit base64 key using a tool like openssl: openssl rand -base64 32.

  • The &Cookies request guard has been removed in favor of Cookies

    Change &Cookies in a request guard position to Cookies.

  • Rocket::launch() now returns a LaunchError, doesn't panic.

    For the old behavior, suffix a call to .launch() with a semicolon: .launch();.

  • Routes without query parameters match requests with or without query parameters.

    There is no workaround, but this change may allow manual ranks from routes to be removed.

  • The format route attribute on non-payload requests matches against the Accept header.

    Excepting a custom request guard, there is no workaround. Previously, format always matched against the Content-Type header, regardless of whether the request method indicated a payload or not.

  • A type of &str can no longer be used in form structures or parameters.

    Use the new &RawStr type instead.

  • ContentType is no longer a request guard.

    Use &ContentType instead.

  • Request::content_type() returns &ContentType instead of ContentType.

    Use .clone() on &ContentType if a type of ContentType is required.

  • Response::header_values() was removed. Response::headers() now returns an &HeaderMap.

    A call to Response::headers() can be replaced with Response::headers().iter(). A call to Response::header_values(name) can be replaced with Response::headers().get(name).

  • Route collisions result in a hard error and panic.

    There is no workaround. Previously, route collisions were a warning.

  • The IntoOutcome trait has been expanded and made more flexible.

    There is no workaround. IntoOutcome::into_outcome() now takes a Failure value to use. IntoOutcome::or_forward() was added to return a Forward outcome if self indicates an error.

  • The 'testing' feature was removed.

    Remove features = ["testing"] from Cargo.toml. Use the new local module for testing.

  • serde was updated to 1.0.

    There is no workaround. Ensure all dependencies rely on serde 1.0.

  • config::active() was removed.

    Use Rocket::config() to retrieve the configuration before launch. If needed, use managed state to store config information for later use.

  • The Responder trait has changed.

    Responder::respond(self) was removed in favor of Responder::respond_to(self, &Request). Responders may dynamically adjust their response based on the incoming request.

  • Outcome::of(Responder) was removed while Outcome::from(&Request, Responder) was added.

    Use Outcome::from(..) instead of Outcome::of(..).

  • Usage of templates requires Template::fairing() to be attached.

    Call .attach(Template::fairing()) on the application's Rocket instance before launching.

  • The Display implementation of Template was removed.

    Use Template::show() to render a template directly.

  • Request::new() is no longer exported.

    There is no workaround.

  • The FromForm trait has changed.

    Responder::from_form_items(&mut FormItems) was removed in favor of Responder::from_form(&mut FormItems, bool). The second parameter indicates whether parsing should be strict (if true) or lenient (if false).

  • LoggingLevel was removed as a root reexport.

    It can now be imported from rocket::config::LoggingLevel.

  • An Io variant was added to ConfigError.

    Ensure matches on ConfigError include an Io variant.

  • ContentType::from_extension() returns an Option<ContentType>.

    For the old behavior, use .unwrap_or(ContentType::Any).

  • The IntoValue config trait was removed in favor of Into<Value>.

    There is no workaround. Use Into<Value> as necessary.

  • The rocket_contrib::JSON type has been renamed to rocket_contrib::Json.

    Use Json instead of JSON.

  • All structs in the content module use TitleCase names.

    Use Json, Xml, Html, and Css instead of JSON, XML, HTML, and CSS, respectively.

General Improvements

  • "Rocket" is now capitalized in the Server HTTP header.
  • The generic parameter of rocket_contrib::Json defaults to json::Value.

Breaking Changes

This release includes several breaking changes. These changes are listed below along with a short note about how to handle the breaking change in existing applications.

  • Rocket::custom takes two parameters, the first being Config by value.

    A call in v0.1 of the form Rocket::custom(&config) is now Rocket::custom(config, false).

  • Tera templates are named without their extension.

    A templated named name.html.tera is now simply name.

  • JSON unwrap method has been renamed to into_inner.

    A call to .unwrap() should be changed to .into_inner().

  • The map! macro was removed in favor of the json! macro.

    A call of the form map!{ "a" => b } can be written as: json!({ "a": b }).

  • The hyper::SetCookie header is no longer exported.

    Use the Cookie type as an Into<Header> type directly.

  • The Content-Type for String is now text/plain.

    Use content::HTML<String> for HTML-based String responses.

  • Request.content_type() returns an Option<ContentType>.

    Use .unwrap_or(ContentType::Any) to get the old behavior.

  • The ContentType request guard forwards when the request has no Content-Type header.

    Use an Option<ContentType> and .unwrap_or(ContentType::Any) for the old behavior.

  • A Rocket instance must be declared before a MockRequest.

    Change the order of the rocket::ignite() and MockRequest::new() calls.

  • A route with format specified only matches requests with the same format.

    Previously, a route with a format would match requests without a format specified. There is no workaround to this change; simply specify formats when required.

  • FormItems can no longer be constructed directly.

    Instead of constructing as FormItems(string), construct as FormItems::from(string).

  • from_from_string(&str) in FromForm removed in favor of from_form_items(&mut FormItems).

    Most implementation should be using FormItems internally; simply use the passed in FormItems. In other cases, the form string can be retrieved via the inner_str method of FormItems.

  • Config::{set, default_for} are deprecated.

    Use the set_{param} methods instead of set, and new or build in place of default_for.

  • Route paths must be absolute.

    Prepend a / to convert a relative path into an absolute one.

  • Route paths cannot contain empty segments.

    Remove any empty segments, including trailing ones, from a route path.

Bug Fixes

A couple of bugs were fixed in this release:

  • Handlebars partials were not properly registered (#122).
  • Rocket::custom did not set the custom configuration as the active configuration.

Streaming Requests

All incoming request data is now streamed. This resulted in a major change to the Rocket APIs. They are summarized through the following API changes:

  • The form route parameter has been removed.
  • The data route parameter has been introduced.
  • Forms are now handled via the data parameter and Form type.
  • Removed the data parameter from Request.
  • Added FromData conversion trait and default implementation.
  • FromData is used to automatically derive the data parameter.
  • Responders are now final: they cannot forward to other requests.
  • Responsers may only forward to catchers.

Breaking

  • Request uri parameter is private. Use uri() method instead.
  • form module moved under request module.
  • response::data was renamed to response::content.
  • Introduced Outcome with Success, Failure, and Forward variants.
  • outcome module moved to top-level.
  • Response is now a type alias to Outcome.
  • Empty Responder was removed.
  • StatusResponder removed in favor of response::status module.

Codegen

  • Error handlers can now take 0, 1, or 2 parameters.
  • FromForm derive now works on empty structs.
  • Lifetimes are now properly stripped in code generation.
  • Any valid ident is now allowed in single-parameter route parameters.

Core

  • Route is now cloneable.
  • Request no longer has any lifetime parameters.
  • Handler type now includes a Data parameter.
  • http module is public.
  • Responder implemented for () type as an empty response.
  • Add config::get() for global config access.
  • Introduced testing module.
  • Rocket.toml allows global configuration via [global] table.

Docs

  • Added a raw_upload example.
