Struct actix_web::http::header::LastModified

source · [−]

pub struct LastModified(pub HttpDate);

Expand description

Last-Modified header, defined in RFC 7232 §2.2

The Last-Modified header field in a response provides a timestamp indicating the date and time at which the origin server believes the selected representation was last modified, as determined at the conclusion of handling the request.

ABNF

Expires = HTTP-date

Example Values

Sat, 29 Oct 1994 19:43:31 GMT

Examples

use std::time::{SystemTime, Duration};
use actix_web::HttpResponse;
use actix_web::http::header::LastModified;

let mut builder = HttpResponse::Ok();
let modified = SystemTime::now() - Duration::from_secs(60 * 60 * 24);
builder.insert_header(
    LastModified(modified.into())
);
