* Introduce IntoResponseHeaders trait
* Implement IntoResponseHeaders for HeaderMap
* Add impl IntoResponse for impl IntoResponseHeaders
… and update IntoResponse impls that use HeaderMap to be generic instead.
* Add impl IntoResponseHeaders for Headers
… and remove IntoResponse impls that use it.
* axum-debug: Fix grammar in docs
* Explain confusing error message in docs
* Fix inconsistent indentation in axum/Cargo.toml
* Make MatchedPath and OriginalUri extractors and logic for them optional
… they add some runtime cost to handling any request that goes through
a Router, which only makes sense if they actually get used.
Enable both features by default for convenience.
* Simplify json content-type check
* Import HeaderMap from http instead of from headers
The headers crate is an optional dependency and its HeaderMap re-export
is `#[doc(hidden)]`.
* Use headers re-export in axum in examples
* 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.
