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.
In #363 I added `MaybeSharedNode` which makes `Router` faster to clone
_if_ you're using `into_make_service`. However I would like instead like
to find a solution that works even when you're not using
`into_make_service`.
Using an `Arc<RwLock<Node<_>>>` is probably the only solution but would
like to experiment. For now I'm gonna rollback `MaybeSharedNode`.
Changing it wont require user facing changes.

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.

* Percent decode automatically in `extract::Path`
Fixes https://github.com/tokio-rs/axum/issues/261
* return an error if path param contains invalid utf-8
* Mention automatic decoding in the docs
* Update changelog: This is a breaking change
* cleanup
* fix tests
* Improve performance of `BoxRoute`
This is based on #315 but slightly shorter.
It removes the need for a `tower::buffer::Buffer` in `BoxRoute` which
improves performance.

This changes the test setup to use our own client rather than using
reqwest directly. Allows us to add several quality of life features like
always unwrapping results.
* Improve extractor docs
- Moves things from the `extract` module docs to the root module docs to
make them more discoverable
- Adds section showing commonly used extractors
- More clarity around multiple extractors that mutate the request

Boxing a service normally means using `tower::util::BoxService`. That
doesn't implement `Clone` however so normally I had been combining it
with `Buffer` to get that.
But recently I discovered https://github.com/dtolnay/dyn-clone which
makes it possible to clone trait objects. So this adds a new internal
utility called `CloneBoxService` which replaces the previous
`BoxService` + `Buffer` combo in `BoxRoute`.
I'll investigate upstreaming that to tower. I think it makes sense there
since box + clone is quite a common need.
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`.
This adds `StreamBody` which converts a `Stream` of `Bytes` into a `http_body::Body`.
---
As suggested by Kestrer on Discord it would make sense for axum to provide different kinds of body types other than `Empty`, `Full`, and `hyper::Body`. There is also some talk about [splitting up `hyper::Body`](https://github.com/hyperium/hyper/issues/2345) so this can be seen as getting started on that effort. axum's body types could be moved to hyper or http-body if thats the direction we decide on.
The types I'm thinking about adding are:
- `StreamBody`- added in this PR
- `AsyncReadBody` - similar to [http-body#41](https://github.com/hyperium/http-body/pull/41/files)
- `ChannelBody` - similar to `hyper::Body::channel`
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.
I haven't been able to find a proper solution for #89 so for now I think
we should document the issue and move on with shipping 0.2.
