* 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.

* fix CI
* Clean up axum-debug crate
Mostly just brings the crate more in line with the rest of the crates in
the workspace.
I've also removed the axum-debug-macros crate since axum-debug only
contained one re-export from axum-debug-macros. So we didn't need two
crates. Can always bring the "backend" crate back if we need things in
axum-debug that aren't proc-macros.

a tab has leaked into workspace Cargo.toml, it must be fixed
* address clippy warnings
* 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.

not needed since readme in repo root is now a symlink
* Revert "Add licenses to all examples"
This reverts commit ab321b7fb9.
As we learned [in Tonic] bodies don't need to be `Sync` because they can
only be polled from one thread at a time.
This changes axum's bodies to no longer require `Sync` and makes
`BoxBody` an alias for `UnsyncBoxBody<Bytes, axum::Error>`.
[in Tonic]: https://github.com/hyperium/tonic/issues/117
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.
axum uses `impl Layer for ServiceBuilder` internally which requires
tower 0.4.10. Making that explicit should help users updating to axum
0.3 without also having to manually bump their tower dependency.
- 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.

0.2.3 (26. August, 2021)
- **fixed:** Fix accidental breaking change introduced by internal refactor.
`BoxRoute` used to be `Sync` but was accidental made `!Sync` ([#273](https://github.com/tokio-rs/axum/pull/273))
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.
- Overall:
- **fixed:** Overall compile time improvements. If you're having issues with compile time
please file an issue! ([#184](https://github.com/tokio-rs/axum/pull/184)) ([#198](https://github.com/tokio-rs/axum/pull/198)) ([#220](https://github.com/tokio-rs/axum/pull/220))
- **changed:** Remove `prelude`. Explicit imports are now required ([#195](https://github.com/tokio-rs/axum/pull/195))
- Routing:
- **added:** Add dedicated `Router` to replace the `RoutingDsl` trait ([#214](https://github.com/tokio-rs/axum/pull/214))
- **added:** Add `Router::or` for combining routes ([#108](https://github.com/tokio-rs/axum/pull/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](https://github.com/tokio-rs/axum/pull/224))
- **fixed:** `get` routes will now also be called for `HEAD` requests but will always have
the response body removed ([#129](https://github.com/tokio-rs/axum/pull/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](https://github.com/tokio-rs/axum/pull/215))
- **changed:** Implement `routing::MethodFilter` via [`bitflags`](https://crates.io/crates/bitflags) ([#158](https://github.com/tokio-rs/axum/pull/158))
- **changed:** Move `handle_error` from `ServiceExt` to `service::OnMethod` ([#160](https://github.com/tokio-rs/axum/pull/160))
With these changes this app using 0.1:
```rust
use axum::{extract::Extension, prelude::*, routing::BoxRoute, AddExtensionLayer};
let app = route("/", get(|| async { "hi" }))
.nest("/api", api_routes())
.layer(AddExtensionLayer::new(state));
fn api_routes() -> BoxRoute<Body> {
route(
"/users",
post(|Extension(state): Extension<State>| async { "hi from nested" }),
)
.boxed()
}
```
Becomes this in 0.2:
```rust
use axum::{
extract::Extension,
handler::{get, post},
routing::BoxRoute,
Router,
};
let app = Router::new()
.route("/", get(|| async { "hi" }))
.nest("/api", api_routes());
fn api_routes() -> Router<BoxRoute> {
Router::new()
.route(
"/users",
post(|Extension(state): Extension<State>| async { "hi from nested" }),
)
.boxed()
}
```
- Extractors:
- **added:** Make `FromRequest` default to being generic over `body::Body` ([#146](https://github.com/tokio-rs/axum/pull/146))
- **added:** Implement `std::error::Error` for all rejections ([#153](https://github.com/tokio-rs/axum/pull/153))
- **added:** Add `OriginalUri` for extracting original request URI in nested services ([#197](https://github.com/tokio-rs/axum/pull/197))
- **added:** Implement `FromRequest` for `http::Extensions` ([#169](https://github.com/tokio-rs/axum/pull/169))
- **added:** Make `RequestParts::{new, try_into_request}` public so extractors can be used outside axum ([#194](https://github.com/tokio-rs/axum/pull/194))
- **added:** Implement `FromRequest` for `axum::body::Body` ([#241](https://github.com/tokio-rs/axum/pull/241))
- **changed:** Removed `extract::UrlParams` and `extract::UrlParamsMap`. Use `extract::Path` instead ([#154](https://github.com/tokio-rs/axum/pull/154))
- **changed:** `extractor_middleware` now requires `RequestBody: Default` ([#167](https://github.com/tokio-rs/axum/pull/167))
- **changed:** Convert `RequestAlreadyExtracted` to an enum with each possible error variant ([#167](https://github.com/tokio-rs/axum/pull/167))
- **changed:** `extract::BodyStream` is no longer generic over the request body ([#234](https://github.com/tokio-rs/axum/pull/234))
- **changed:** `extract::Body` has been renamed to `extract::RawBody` to avoid conflicting with `body::Body` ([#233](https://github.com/tokio-rs/axum/pull/233))
- **changed:** `RequestParts` changes ([#153](https://github.com/tokio-rs/axum/pull/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](https://github.com/tokio-rs/axum/pull/153)) ([#154](https://github.com/tokio-rs/axum/pull/154))
- Responses:
- **added:** Add `Headers` for easily customizing headers on a response ([#193](https://github.com/tokio-rs/axum/pull/193))
- **added:** Add `Redirect` response ([#192](https://github.com/tokio-rs/axum/pull/192))
- **added:** Add `body::StreamBody` for easily responding with a stream of byte chunks ([#237](https://github.com/tokio-rs/axum/pull/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](https://github.com/tokio-rs/axum/pull/86))
- **changed:** `tower::util::Either` no longer implements `IntoResponse` ([#229](https://github.com/tokio-rs/axum/pull/229))
This `IntoResponse` from 0.1:
```rust
use axum::{http::Response, prelude::*, response::IntoResponse};
struct MyResponse;
impl IntoResponse for MyResponse {
fn into_response(self) -> Response<Body> {
Response::new(Body::empty())
}
}
```
Becomes this in 0.2:
```rust
use axum::{body::Body, http::Response, response::IntoResponse};
struct MyResponse;
impl IntoResponse for MyResponse {
type Body = Body;
type BodyError = <Self::Body as axum::body::HttpBody>::Error;
fn into_response(self) -> Response<Self::Body> {
Response::new(Body::empty())
}
}
```
- SSE:
- **added:** Add `response::sse::Sse`. This implements SSE using a response rather than a service ([#98](https://github.com/tokio-rs/axum/pull/98))
- **changed:** Remove `axum::sse`. Its been replaced by `axum::response::sse` ([#98](https://github.com/tokio-rs/axum/pull/98))
Handler using SSE in 0.1:
```rust
use axum::{
prelude::*,
sse::{sse, Event},
};
use std::convert::Infallible;
let app = route(
"/",
sse(|| async {
let stream = futures::stream::iter(vec![Ok::<_, Infallible>(
Event::default().data("hi there!"),
)]);
Ok::<_, Infallible>(stream)
}),
);
```
Becomes this in 0.2:
```rust
use axum::{
handler::get,
response::sse::{Event, Sse},
Router,
};
use std::convert::Infallible;
let app = Router::new().route(
"/",
get(|| async {
let stream = futures::stream::iter(vec![Ok::<_, Infallible>(
Event::default().data("hi there!"),
)]);
Sse::new(stream)
}),
);
```
- WebSockets:
- **changed:** Change WebSocket API to use an extractor plus a response ([#121](https://github.com/tokio-rs/axum/pull/121))
- **changed:** Make WebSocket `Message` an enum ([#116](https://github.com/tokio-rs/axum/pull/116))
- **changed:** `WebSocket` now uses `Error` as its error type ([#150](https://github.com/tokio-rs/axum/pull/150))
Handler using WebSockets in 0.1:
```rust
use axum::{
prelude::*,
ws::{ws, WebSocket},
};
let app = route(
"/",
ws(|socket: WebSocket| async move {
// do stuff with socket
}),
);
```
Becomes this in 0.2:
```rust
use axum::{
extract::ws::{WebSocket, WebSocketUpgrade},
handler::get,
Router,
};
let app = Router::new().route(
"/",
get(|ws: WebSocketUpgrade| async move {
ws.on_upgrade(|socket: WebSocket| async move {
// do stuff with socket
})
}),
);
```
- Misc
- **added:** Add default feature `tower-log` which exposes `tower`'s `log` feature. ([#218](https://github.com/tokio-rs/axum/pull/218))
- **changed:** Replace `body::BoxStdError` with `axum::Error`, which supports downcasting ([#150](https://github.com/tokio-rs/axum/pull/150))
- **changed:** `EmptyRouter` now requires the response body to implement `Send + Sync + 'static'` ([#108](https://github.com/tokio-rs/axum/pull/108))
- **changed:** `Router::check_infallible` now returns a `CheckInfallible` service. This
is to improve compile times ([#198](https://github.com/tokio-rs/axum/pull/198))
- **changed:** `Router::into_make_service` now returns `routing::IntoMakeService` rather than
`tower::make::Shared` ([#229](https://github.com/tokio-rs/axum/pull/229))
- **changed:** All usage of `tower::BoxError` has been replaced with `axum::BoxError` ([#229](https://github.com/tokio-rs/axum/pull/229))
- **changed:** Several response future types have been moved into dedicated
`future` modules ([#133](https://github.com/tokio-rs/axum/pull/133))
- **changed:** `EmptyRouter`, `ExtractorMiddleware`, `ExtractorMiddlewareLayer`,
and `QueryStringMissing` no longer implement `Copy` ([#132](https://github.com/tokio-rs/axum/pull/132))
- **changed:** `service::OnMethod`, `handler::OnMethod`, and `routing::Nested` have new response future types ([#157](https://github.com/tokio-rs/axum/pull/157))
* Feature-gate test that depends on non-default features
Makes `cargo check` work without extra flags.
* Don't set doc(html_root_url)
It is no longer recommended:
https://github.com/rust-lang/api-guidelines/pull/230
* Remove documentation URL from Cargo.toml
crates.io will link to the right version on docs.rs automatically.
* Ensure toolchains installed by actions-rs/toolchain are actually used
* Fix missing rustup component in check job
* Raise MSRV to 1.51
Older versions weren't actually working before.
* Only run clippy & rustfmt on stable toolchain
MSRV is checked in test-versions.
* Allow cargo doc to succeed without headers and multipart features
CI will still ensure that intra-doc links that rely on these are not broken.
