TypedHeader

tako::extractors::typed_header

Struct TypedHeader

pub struct TypedHeader<H>(pub H);

Available on crate feature typed-header only.

Expand description

A strongly-typed header extractor.

H must implement headers::Header (e.g. headers::UserAgent, headers::ContentType, headers::Authorization<Bearer>).
