David Pedersen a753eac23f Remove boxing from StreamBody (#241) 
I just had a thought: Why should `response::Headers` be generic, but
`body::StreamBody` should not? `StreamBody` previously boxed the stream
to erase the generics. So we had `response::Headers<T>` but
`body::StreamBody`, without generics.

After thinking about it I think it actually makes sense for responses to
remain generic because you're able to use `impl IntoResponse` so you
don't have to name the generics.

Whereas in the case of `BodyStream` (an extractor) you cannot use `impl Trait`
so it makes sense to box the inner body to make the type easier to name. Besides,
`BodyStream` is mostly useful when the request body isn't `hyper::Body`, as
that already implements `Stream`.

Unreleased

  • Overall:
    • added: Add default feature tower-log which exposes tower's log feature. (#218)
    • fixed: Overall compile time improvements. If you're having issues with compile time please file an issue! (#184) (#198) (#220)
    • fixed: Remove prelude. Explicit imports are now required (#195)
    • changed: Replace body::BoxStdError with axum::Error, which supports downcasting (#150)
  • 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)
  • 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)
  • 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)
  • 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)
  • Misc
    • 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)
