0.2.0 (23. August, 2021)

Overall:
- fixed: Overall compile time improvements. If you're having issues with compile time
  please file an issue! (#184) (#198) (#220)
- changed: Remove prelude. Explicit imports are now required (#195)

Routing:

added: Add dedicated Router to replace the RoutingDsl trait (#214)
added: Add Router::or for combining routes (#108)
fixed: Support matching different HTTP methods for the same route that aren't defined
together. So Router::new().route("/", get(...)).route("/", post(...)) now
accepts both GET and POST. Previously only POST would be accepted (#224)
fixed: get routes will now also be called for HEAD requests but will always have
the response body removed (#129)
changed: Replace axum::route(...) with axum::Router::new().route(...). This means
there is now only one way to create a new router. Same goes for
axum::routing::nest. (#215)
changed: Implement routing::MethodFilter via bitflags (#158)
changed: Move handle_error from ServiceExt to service::OnMethod (#160)

With these changes this app using 0.1:

use axum::{extract::Extension, prelude::*, routing::BoxRoute, AddExtensionLayer};

let app = route("/", get(|| async { "hi" }))
    .nest("/api", api_routes())
    .layer(AddExtensionLayer::new(state));

fn api_routes() -> BoxRoute<Body> {
    route(
        "/users",
        post(|Extension(state): Extension<State>| async { "hi from nested" }),
    )
    .boxed()
}

Becomes this in 0.2:

use axum::{
    extract::Extension,
    handler::{get, post},
    routing::BoxRoute,
    Router,
};

let app = Router::new()
    .route("/", get(|| async { "hi" }))
    .nest("/api", api_routes());

fn api_routes() -> Router<BoxRoute> {
    Router::new()
        .route(
            "/users",
            post(|Extension(state): Extension<State>| async { "hi from nested" }),
        )
        .boxed()
}

Extractors:
- added: Make FromRequest default to being generic over body::Body (#146)
- added: Implement std::error::Error for all rejections (#153)
- added: Add OriginalUri for extracting original request URI in nested services (#197)
- added: Implement FromRequest for http::Extensions (#169)
- added: Make RequestParts::{new, try_into_request} public so extractors can be used outside axum (#194)
- added: Implement FromRequest for axum::body::Body (#241)
- changed: Removed extract::UrlParams and extract::UrlParamsMap. Use extract::Path instead (#154)
- changed: extractor_middleware now requires RequestBody: Default (#167)
- changed: Convert RequestAlreadyExtracted to an enum with each possible error variant (#167)
- changed: extract::BodyStream is no longer generic over the request body (#234)
- changed: extract::Body has been renamed to extract::RawBody to avoid conflicting with body::Body (#233)
- changed: RequestParts changes (#153)
  - method new returns an &http::Method
  - method_mut new returns an &mut http::Method
  - take_method has been removed
  - uri new returns an &http::Uri
  - uri_mut new returns an &mut http::Uri
  - take_uri has been removed
- changed: Remove several rejection types that were no longer used (#153) (#154)

Responses:

added: Add Headers for easily customizing headers on a response (#193)
added: Add Redirect response (#192)
added: Add body::StreamBody for easily responding with a stream of byte chunks (#237)
changed: Add associated Body and BodyError types to IntoResponse. This is
required for returning responses with bodies other than hyper::Body from
handlers. See the docs for advice on how to implement IntoResponse (#86)
changed: tower::util::Either no longer implements IntoResponse (#229)

This IntoResponse from 0.1:

use axum::{http::Response, prelude::*, response::IntoResponse};

struct MyResponse;

impl IntoResponse for MyResponse {
    fn into_response(self) -> Response<Body> {
        Response::new(Body::empty())
    }
}

Becomes this in 0.2:

use axum::{body::Body, http::Response, response::IntoResponse};

struct MyResponse;

impl IntoResponse for MyResponse {
    type Body = Body;
    type BodyError = <Self::Body as axum::body::HttpBody>::Error;

    fn into_response(self) -> Response<Self::Body> {
        Response::new(Body::empty())
    }
}

SSE:

added: Add response::sse::Sse. This implements SSE using a response rather than a service (#98)
changed: Remove axum::sse. Its been replaced by axum::response::sse (#98)

Handler using SSE in 0.1:

use axum::{
    prelude::*,
    sse::{sse, Event},
};
use std::convert::Infallible;

let app = route(
    "/",
    sse(|| async {
        let stream = futures::stream::iter(vec![Ok::<_, Infallible>(
            Event::default().data("hi there!"),
        )]);
        Ok::<_, Infallible>(stream)
    }),
);

Becomes this in 0.2:

use axum::{
    handler::get,
    response::sse::{Event, Sse},
    Router,
};
use std::convert::Infallible;

let app = Router::new().route(
    "/",
    get(|| async {
        let stream = futures::stream::iter(vec![Ok::<_, Infallible>(
            Event::default().data("hi there!"),
        )]);
        Sse::new(stream)
    }),
);

WebSockets:

changed: Change WebSocket API to use an extractor plus a response (#121)
changed: Make WebSocket Message an enum (#116)
changed: WebSocket now uses Error as its error type (#150)

Handler using WebSockets in 0.1:

use axum::{
    prelude::*,
    ws::{ws, WebSocket},
};

let app = route(
    "/",
    ws(|socket: WebSocket| async move {
        // do stuff with socket
    }),
);

Becomes this in 0.2:

use axum::{
    extract::ws::{WebSocket, WebSocketUpgrade},
    handler::get,
    Router,
};

let app = Router::new().route(
    "/",
    get(|ws: WebSocketUpgrade| async move {
        ws.on_upgrade(|socket: WebSocket| async move {
            // do stuff with socket
        })
    }),
);

Misc
- added: Add default feature tower-log which exposes tower's log feature. (#218)
- changed: Replace body::BoxStdError with axum::Error, which supports downcasting (#150)
- changed: EmptyRouter now requires the response body to implement Send + Sync + 'static' (#108)
- changed: Router::check_infallible now returns a CheckInfallible service. This
  is to improve compile times (#198)
- changed: Router::into_make_service now returns routing::IntoMakeService rather than
  tower::make::Shared (#229)
- changed: All usage of tower::BoxError has been replaced with axum::BoxError (#229)
- changed: Several response future types have been moved into dedicated
  future modules (#133)
- changed: EmptyRouter, ExtractorMiddleware, ExtractorMiddlewareLayer,
  and QueryStringMissing no longer implement Copy (#132)
- changed: service::OnMethod, handler::OnMethod, and routing::Nested have new response future types (#157)
