* Add sqlx example with migrations
Simple use case for sqlx based on tokio postgres example.
Sqlite database is created on execution in ./target directory
and migrations are then run against it.
* sqlx example uses postgres instead of sqlite3
Also removed migrations and database creation code.

* fix docs
* changelog
* inline variable
* also add changelog item to axum
* don't list types from axum in axum-core's changelog
* document that `HeaderMap::from_request` clones the headers
* fix typo
* a few more typos
* Use 308 status instead of 301 when redirecting
For redirects resulting from requests to paths with a trailing slash,
use 308 instead of 301 to prevent non-GET requests (POST, PUT, etc) from
being changed to GET.
For example, (assuming a route for /path is defined)...
- Old behavior results in:
POST /path/ -> GET /path
- New behavior results in:
POST /path/ -> POST /path
Fixes#681
* Add deprecation notice to found()
Deprecates found() due to its use of HTTP 302
* rustfmt
* Use dedicated redirect method
Use Redirect::permanent instead of re-implementing its functionality
* Remove deprecated method from example
Replace usages of Redirect:found with Redirect::to and Redirect::temporary as appropriate
* Fix panic in oauth example
Previously the example would panic if a request was made without the
`Cookie` header. Now the user is redirected to the login page as
expected.

The headers crate is an optional dependency and its HeaderMap re-export
is `#[doc(hidden)]`.

* Add `middleware::from_fn` for creating middleware from async fns
* More trait impls for `Next`
* Make `Next::run` consume `self`

* Move `axum-handle-error-extract` into axum
With 0.4 underway we can now nuke `axum-handle-error-extract` and move
its code directly into axum.
So this replaces the old `HandleErrorLayer` with one that supports async
functions and extractors.

* Move axum crate into workspace subfolder
Over time I imagine we're gonna have other crates in this repo that
provide utilities or integrations for axum. This prepares for that by
moving the main axum crate into its own folder.
The README situation is a bit annoying because we want `./README.md`
for viewing the repo on github but `axum/README.md` for crates.io. For
now I've just copy/pasted it and added CI step to make sure they're
identical.
* update changelog link

This reworks axum's docs in an attempt to make things easier to find. Previously I wasn't a fan of those docs for the same topic were spread across the root module docs and more specific places like types and methods.
This changes it such that the root module docs only gives a high level introduction to a topic, perhaps with a small example, and then link to other places where all the details are. This means `Router` is now the single place to learn about routing, and etc for the topics like handlers and error handling.
With https://github.com/tokio-rs/axum/pull/404 and https://github.com/tokio-rs/axum/pull/402 all routes now have the same types and thus we don't need to nest them but can instead store them all in a map. This simplifies the routing quite a bit and is faster as well.
High level changes:
- Routes are now stored in a `HashMap<RouteId, Route<B>>`.
- `Router::or` is renamed to `Router::merge` because thats what it does now. It copies all routes from one router to another. This also means overlapping routes will cause a panic which is nice win.
- `Router::merge` now only accepts `Router`s so added `Router::fallback` for adding a global 404 handler.
- The `Or` service has been removed.
- `Router::layer` now only adds layers to the routes you actually have meaning middleware runs _after_ routing. I believe that addresses https://github.com/tokio-rs/axum/issues/380 but will test that on another branch.
I've been thinking that having an associated type probably isn't
necessary. I imagine most users are either using `SocketAddr` to the
remote connection IP, or writing their own connection struct.
## Motivation
Current `tls-rustls` example might be inconvenient for some people.
## Solution
Rename current example to `low-level-rustls` and add a high level example in its place.
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);
```
Previously, on `main`, this wouldn't compile:
```rust
let app = route("/", get(handler))
.layer(
ServiceBuilder::new()
.timeout(Duration::from_secs(10))
.into_inner(),
)
.handle_error(...)
.route(...); // <-- doesn't work
```
That is because `handle_error` would be
`axum::service::ServiceExt::handle_error` which returns `HandleError<_,
_, _, HandleErrorFromService>` which does _not_ implement `RoutingDsl`.
So you couldn't call `route`. This was caused by
https://github.com/tokio-rs/axum/pull/120.
Basically `handle_error` when called on a `RoutingDsl`, the resulting
service should also implement `RoutingDsl`, but if called on another
random service it should _not_ implement `RoutingDsl`.
I don't think thats possible by having `handle_error` on `ServiceExt`
which is implemented for any service, since all axum routers are also
services by design.
This resolves the issue by removing `ServiceExt` and moving its methods
to `RoutingDsl`. Then we have more tight control over what has a
`handle_error` method.
`service::OnMethod` now also has a `handle_error` so you can still
handle errors from random services, by doing
`service::any(svc).handle_error(...)`.
* feat(ws): make Message an enum to allow pattern matching
* fix(examples): update to new websockets `Message`
* fix(ws): remove wildcard imports
* fix(examples/chat): apply clippy's never_loop
* style: `cargo fmt`
* docs:add license notes above parts that are copied
* fix(ws): make CloseCode an alias to u16
* fix: move Message from src/ws/mod.rs to src/extract/ws.rs
* docs: add changelog entry about websocket messages
* fix: remove useless convertions to the same type
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.

Example usage:
```rust
use axum::{prelude::*, sse::{sse, Event, KeepAlive}};
use tokio_stream::StreamExt as _;
use futures::stream::{self, Stream};
use std::{
time::Duration,
convert::Infallible,
};
let app = route("/sse", sse(make_stream).keep_alive(KeepAlive::default()));
async fn make_stream(
// you can also put extractors here
) -> Result<impl Stream<Item = Result<Event, Infallible>>, Infallible> {
// A `Stream` that repeats an event every second
let stream = stream::repeat_with(|| Event::default().data("hi!"))
.map(Ok)
.throttle(Duration::from_secs(1));
Ok(stream)
}
```
Implementation is based on [warp's](https://github.com/seanmonstar/warp/blob/master/src/filters/sse.rs)
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`.
Not actually related to Axum, can be implemented directly with Hyper, but I figure its nice to have for demonstration and might help catch accidental breaking changes in the future.
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.
This changes error model to actually allow errors. I think if we're going to use this for things like tonic's route we need a more flexible error handling model. The same `handle_error` adaptors are still there but services aren't required to have `Infallible` as their error type. The error type is simply propagated all the way through.
Previously, when routing between one or two requests the two body types
would be merged by boxing them. This isn't ideal since it introduces a
layer indirection for each route.
We can't require the services to be routed between as not all services
use the same body type.
This changes that so it instead uses an `Either` enum that implements
`http_body::Body` if each variant does. Will reduce the overall
allocations and hopefully the compiler can optimize things if both
variants are the same.
