When fixing bugs with `MatchedPath` (introduced to fix https://github.com/tokio-rs/axum/issues/386) I realized nesting could basically be implemented using regular routes, if we can detect that the service passed to `nest` is in fact a `Router`. Then we can transfer over all its routes and add the prefix.
This makes nesting much simpler in general and should also be slightly faster since we're no longer nesting routers.
We stripped the prefix before calling any middleware. Instead the prefix
should be stripped just before calling the actual route. This way
middleware still see the full URI, as it used to work in 0.2.
Fixes#419
While thinking about #419 I realized that `main` had a bug where
middleware wouldn't be called if no route matched the incoming request.
`Router` would just directly return a 404 without calling any
middleware.
This fixes by making the fallback default to a service that always
returns 404 and always calling that if no route matches.
Layers applied to the router is then also applied to the fallback.
Unfortunately this breaks #380 but I don't currently see a way to
support both. Auth middleware need to run _after_ routing because you
don't care about auth for unknown paths, but logging middleware need to
run _before_ routing because they do care about seeing requests for
unknown paths so they can log them...
Part of #419
- Static vs dynamic paths are now supported meaning `/foo` and `/:key`
are not considered to overlap.
- A bug we hit regarding trailing slashes is fixed.
This remove tower-http from axum's public API. I would like to be able
to make breaking releases of tower-http without also having to ship a
breaking release of axum.
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.
* changelog
