This adds an internal ability to copy the HTTP/1 reason-phrase and place it in the `http::Extensions` of a response, if it doesn't match the canonical reason. This could be exposed in the Rust API later, but for now it is only used by the C API.
C API for hyper
This provides auxiliary pieces for a C API to use the hyper library.
Unstable
The C API of hyper is currently unstable, which means it's not part of the semver contract as the rest of the Rust API is.
Because of that, it's only accessible if --cfg hyper_unstable_ffi is passed to rustc when compiling. The easiest way to do that is setting the RUSTFLAGS environment variable.
Building
The C API is part of the Rust library, but isn't compiled by default. Using cargo, it can be compiled with the following command:
RUSTFLAGS="--cfg hyper_unstable_ffi" cargo build --features client,http1,http2,ffi
