Trait headers_core::Header

pub trait Header {
    // Required methods
    fn name() -> &'static HeaderName;
    fn decode<'i, I>(values: &mut I) -> Result<Self, Error>
       where Self: Sized,

}

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 Self: Sized, I: Iterator<Item = &'i HeaderValue>,

Decode this type from an iterator of HeaderValues.

fn encode<E: Extend<HeaderValue>>(&self, values: &mut E)

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.

Object Safety

This trait is not object safe.
