Struct ContentLength

pub struct ContentLength(pub usize);

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));
