[−] 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 name() -> &'static HeaderName[−]

The name of this header.

fn decode<'i, I>(values: &mut I) -> Result<Self, Error> where
    I: Iterator<Item = &'i HeaderValue>, [−]

Decode this type from an iterator of HeaderValues.

fn encode<E>(&self, values: &mut E) where
    E: Extend<HeaderValue>, [−]

Encode this type to a HeaderMap.

This function should be infallible. Any errors converting to a HeaderValue should have been caught when parsing or constructing this value.
