Struct actix_web::http::header::Expires

pub struct Expires(pub HttpDate);

Expires header, defined in RFC7234

The Expires header field gives the date/time after which the response is considered stale.

The presence of an Expires field does not imply that the original resource will change or cease to exist at, before, or after that time.
