Struct actix_web::http::header::Expires

pub struct Expires(pub HttpDate);

Expires header, defined in RFC 7234 §5.3

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.

ABNF

Expires = HTTP-date

builder.insert_header(
    Expires(expiration.into())
);

Formats the value using the given formatter.

impl Deref for Expires

type Target = HttpDate

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for Expires
