pub struct ContentLength(pub usize);
Expand description

Content-Length header, defined in RFC 9110 §8.6.

The Content-Length

§ABNF

Content-Length = 1*DIGIT

§Example Values

  • 0
  • 3495

§Examples

use actix_web::{http::header::ContentLength, HttpResponse};

let res_empty = HttpResponse::Ok()
    .insert_header(ContentLength(0));

let res_fake_cl = HttpResponse::Ok()
    .insert_header(ContentLength(3_495));
