}
Expand description
A trait for any object that will represent a header field and value.
This trait represents the construction and identification of headers, and contains trait-object unsafe methods.
Required methods
fn header_name() -> &'static str
fn header_name() -> &'static str
Returns the name of the header field this belongs to.
This will become an associated constant once available.
Parse a header from a raw stream of bytes.
It’s possible that a request can include a header field more than once,
and in that case, the slice will have a length greater than 1. However,
it’s not necessarily the case that a Header is allowed to have more
than one field value. If that’s the case, you should return None
if raw.len() > 1
