Enum actix_web::http::header::Preference
source · pub enum Preference<T> {
Any,
Specific(T),
}
Expand description
A wrapper for types used in header values where wildcard (*
) items are allowed but the
underlying type does not support them.
For example, we use the language-tags
crate for the AcceptLanguage
typed header but it does not parse *
successfully. On the other hand, the mime
crate, used
for Accept
, has first-party support for wildcard items so this wrapper is not
used in those header types.
