Support for Rust Stable

As a result of support for Rust stable (Rust 2021 Edition and beyond),
#![feature(..)] crate attributes are no longer required to use Rocket. 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. For a walkthrough guide on handling these changes, see
the v0.4 to v0.5 migration guide. 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.
• ROCKET_ADDRESS accepts only IP addresses, no longer resolves hostnames like localhost.
• ROCKET_CLI_COLORS accepts booleans true, false in place of strings "on", "off".
• 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.
• Hash impls for MediaType and ContentType no longer consider media type parameters.
• When requested, the FromForm implementations of Vec and Maps are now properly lenient.
• To agree with browsers, the [ and ] characters are now accepted in URI paths.
• The [ and ] characters are no longer encoded by uri!.
• The Secure cookie flag is set by default for all cookies when serving over TLS.
• Removal cookies have SameSite set to Lax by default.
• MediaType::JavaScript is now text/javascript.

Contrib Graduation

The rocket_contrib crate is deprecated and the functionality moved to other rocket crates. The
contrib deprecation upgrade guide provides a walkthrough on migrating. The relevant changes are:

• Several features previously in rocket_contrib were merged into rocket itself:
  • json, msgpack, and uuid are now features of rocket.
  • Moved rocket_contrib::json to rocket::serde::json.
  • Moved rocket_contrib::msgpack to rocket::serde::msgpack.
  • Moved rocket_contrib::uuid to rocket::serde::uuid.
  • Moved rocket_contrib::helmet to rocket::shield. Shield is enabled by default.
  • Moved rocket_contrib::serve to rocket::fs, StaticFiles to rocket::fs::FileServer.
  • Removed the now unnecessary Uuid and JsonValue wrapper types.
  • Removed headers in Shield that are no longer respected by browsers.
• 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 and rocket_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.

General

The following breaking changes apply broadly and are likely to cause compile-time errors.

• 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() and 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:
  • FromRequest, Fairing, catcher::Handler, route::Handler, and FromData use
    #[async_trait].
  • NamedFile::open is now an async function.
  • Added Request::local_cache_async() for use in async request guards.
  • Unsized Response bodies must be AsyncRead instead of Read.
  • Automatically sized Response bodies must be AsyncSeek instead of Seek.
  • The local module is split into two: rocket::local::asynchronous and
    rocket::local::blocking.
• Functionality and features requiring Rust nightly were removed:
  • Removed the Try implementation on Outcome which allowed using ? with Outcomes. The
    recommended replacement is the rocket::outcome::try_outcome! macro or the various
    combinator functions on Outcome.
  • Result<T, E> implements Responder only when both T and E implement Responder. The
    new Debug wrapping responder replaces Result<T: Responder, E: Debug>.
  • APIs which used the ! type to now use std::convert::Infallible.
• IntoOutcome was overhauled to supplant methods now removed in Outcome.
  • IntoOutcome::into_outcome() is now or_error().
  • IntoOutcome is implemented for all Outcome type aliases.
  • Outcome::forward() requires specifying a status code.
  • Outcome::from() and Outcome::from_or_forward() 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.
• TLS config values are only available when the tls feature is enabled.
• MediaType::with_params() and ContentType::with_params() are now builder methods.
• Content-Type content responder type names are now prefixed with Raw.
• The content::Plain responder is now called content::RawText.
• The content::Custom<T> responder was removed in favor of (ContentType, T).
• Removed CookieJar::get_private_pending() in favor of CookieJar::get_pending().
• The local_cache! macro accepts fewer types. Use local_cache_once! as appropriate.
• Rocket::launch() allows Rocket recovery by returning the instance after shutdown.
• ErrorKind::Runtime was removed; ErrorKind::Shutdown was added.
• Outcome::Failure was renamed to Outcome::Error.

Routing and URIs

• In #[route(GET, path = "...")], path is now uri: #[route(GET, uri = "...")].
• Multi-segment paths (/<p..>) now match zero or more segments.
• Codegen improvements preclude identically named routes and modules in the same namespace.
• 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().
• The Route::uri field is now of type RouteUri.
• Route::base was removed in favor of Route.uri().base().
• Route Forward outcomes are now associated with a Status.
• The status codes used when built-in guards forward were changed:
  • Route parameter FromParam errors now forward as 422.
  • Query parameter errors now forward as 422.
  • Incorrect form content-type errors forwards as 413.
  • &Host, &Accept, &ContentType, IpAddr, and SocketAddr all forward
    with a 500.

Data and Forms

• Data now has a lifetime generic: Data<'r>.
• Data::open() indelibly requires a data limit.
• Removed FromDataSimple. Use FromData and local_cache! or local_cache_once!.
• 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 = ...)].

• Renamed ResponseBuilder to Builder.
• Removed direct Response body reading methods. Use methods on r.body_mut() instead.
