pub struct Expires(pub HttpDate);
Expand description
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

Examples
use std::time::{SystemTime, Duration};
use actix_web::HttpResponse;
use actix_web::http::header::Expires;
let mut builder = HttpResponse::Ok();
let expiration = SystemTime::now() + Duration::from_secs(60 * 60 * 24);
builder.insert_header(
Expires(expiration.into())
);
