I think `BodyStream` is more useful without being generic over the
request body.
I'm also looking into adding a response body from a stream called
`StreamBody` which will work pretty much opposite to this.
This way there is now only one way to create a router:
```rust
use axum::{Router, handler::get};
let app = Router::new()
.route("/foo", get(handler))
.route("/foo", get(handler));
```
`nest` was changed in the same way:
```rust
use axum::Router;
let app = Router::new().nest("/foo", service);
```
They'd previously see the nested URI as we mutated the request. Now we
always route based on the nested URI (if present) without mutating the
request. Also meant we could get rid of `OriginalUri` which is nice.

Adds associated `Body` and `BodyError` types to `IntoResponse`. This is required for returning responses with bodies other than `hyper::Body` from handlers. That wasn't previously possible.
This is a breaking change so should be shipped in 0.2.
These types were moved around in
https://github.com/tokio-rs/axum/pull/130 but re-export from their old
location for backwards compatibility.
This removes the re-exports.
https://github.com/tokio-rs/axum/pull/129 was a breaking change, in part
because I had to remove the `Copy` impl from `OnMethod`.
For the sake of future proofing I think we should remove other `Copy`
impls from services as well. We can always bring them back once things
have matured more.
These types no longer implement `Copy`:
- `EmptyRouter`
- `ExtractorMiddleware`
- `ExtractorMiddlewareLayer`
It cleans up the docs to have the futures in their own modules as users
are unlikely to look at them. Also matches the pattern used in tower
https://docs.rs/tower/0.4.8/tower/util/future/index.html.
Added re-exports to the old locations so its not a breaking change.
This breaks up `extract.rs` into several smaller submodules. The public
API remains the same.
This is done in prep for adding more tests to extractors which would get
messy if they were all in the same file.
Fixes https://github.com/tokio-rs/axum/issues/43
With this you can get the remote address like so:
```rust
use axum::{prelude::*, extract::ConnectInfo};
use std::net::SocketAddr;
let app = route("/", get(handler));
async fn handler(ConnectInfo(addr): ConnectInfo<SocketAddr>) -> String {
format!("Hello {}", addr)
}
// Starting the app with `into_make_service_with_connect_info` is required
// for `ConnectInfo` to work.
let make_svc = app.into_make_service_with_connect_info::<SocketAddr, _>();
hyper::Server::bind(&"0.0.0.0:3000".parse().unwrap())
.serve(make_svc)
.await
.expect("server failed");
```
This API is fully generic and supports whatever transport layer you're using with Hyper. I've updated the unix domain socket example to extract `peer_creds` and `peer_addr`.
Previously extractors worked directly on `Request<B>` which meant you
had to do weird tricks like `mem::take(req.headers_mut())` to get owned
parts of the request.
This changes that instead to use a new `RequestParts` type that have
methods to "take" each part of the request. Without having to do weird
tricks.
Also removed the need to have `B: Default` for body extractors.
