An implementation of headers::Header for the Accept header as defined in RFC 9110.
Hopefully in the future this can be deprecated in favor of a canonical implentation in the headers library, but that appears not to be a current priority. See hyperium/headers#53.
Because there already exists a different project with the same name on https://crates.io, this is not (yet) published there. Instead, add a git dependency to your project:
accept-header = { version = "0.1.0", git = "https://github.com/coriolinus/accept-header.git" }
