Support `State` with `#[derive(FromRequest[Parts])]` (#1391) * Support `State` with `#[derive(FromRequest[Parts])]` Fixes https://github.com/tokio-rs/axum/issues/1314 This makes it possible to extract things via `State` in `#[derive(FromRequet)]`: ```rust struct Foo { state: State<AppState>, } ``` The state can also be inferred in a lot of cases so you only need to write: ```rust struct Foo { // since we're using `State<AppState>` we know the state has to be // `AppState` state: State<AppState>, } ``` Same for ```rust struct Foo { #[from_request(via(State))] state: AppState, } ``` And ```rust struct AppState {} ``` I think I've covered all the edge cases but there are (unsurprisingly) a few. * make sure things can be combined with other extractors * main functions in ui tests don't need to be async * Add test for multiple identicaly state types * Add failing test for multiple states 2022-09-23 23:50:50 +02:00			`use axum::extract::State;`
