Trait hyper::header::Header [−] [src]

pub trait Header: Clone + Any + Send + Sync {
    fn header_name() -> &'static str;
    fn parse_header(raw: &[Vec<u8>]) -> Result<Self>;
}

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

Returns the name of the header field this belongs to.

This will become an associated constant once available.

fn parse_header(raw: &[Vec<u8>]) -> Result<Self>

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.
