Module hyper::header

Headers container, and common header fields.

hyper has the opinion that Headers should be strongly-typed, because that's why we're using Rust in the first place. To set or get any header, an object must implement the Header trait from this module. Several common headers are already provided, such as Host, ContentType, UserAgent, and others.
