* Reorganize tests
This breaks up the large `crate::tests` module by moving some of the
tests into a place that makes more sense. For example tests of JSON
serialization are moved to the `crate::json` module. The remaining routing
tests have been moved to `crate::routing::tests`.
I generally prefer having tests close to the code they're testing. Makes
it easier to see how/if something is tested.
* Try pinning to older version of async-graphql
* Revert "Try pinning to older version of async-graphql"
This reverts commit 2e2cae7d12f5e433a16d6607497d587863f04384.
* don't test examples on 1.54 on CI
* move ci steps around a bit
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);
```
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.
This breaks up `extract.rs` into several smaller submodules. The public
API remains the same.
This is done in prep for adding more tests to extractors which would get
messy if they were all in the same file.
