Trait headers_core::Header [−][src]
pub trait Header { const NAME: &'static HeaderName; fn decode(values: &mut Values) -> Option<Self>
where
Self: Sized; fn encode(&self, values: &mut ToValues); }
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.
Associated Constants
const NAME: &'static HeaderName
The name of this header.
Required Methods
fn decode(values: &mut Values) -> Option<Self> where
Self: Sized,
Self: Sized,
Decode this type from a HeaderValue
.
fn encode(&self, values: &mut ToValues)
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.
