Trait hyper::header::HeaderExperimental [-]  [+] [src]

pub trait Header: Typeable + Send + Sync {
    fn header_name(marker: Option<Self>) -> &'static str;
    fn parse_header(raw: &[Vec<u8>]) -> Option<Self>;
    fn fmt_header(&self, fmt: &mut Formatter) -> Result;
}

A trait for any object that will represent a header field and value.

Required Methods

fn header_name(marker: Option<Self>) -> &'static str

Returns the name of the header field this belongs to.

The market Option is to hint to the type system which implementation to call. This can be done away with once UFCS arrives.

fn parse_header(raw: &[Vec<u8>]) -> Option<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.

fn fmt_header(&self, fmt: &mut Formatter) -> Result

Format a header to be output into a TcpStream.
