Module content

HTTP Content headers.

These headers are used for “content negotiation”: the client shares information about which content it prefers, and the server responds by sharing which content it’s chosen to share. This enables clients to receive resources with the best available compression, in the preferred language, and more.

Examples

use http_types::content::{Accept, MediaTypeProposal};
use http_types::{mime, Response};

let mut accept = Accept::new();
accept.push(MediaTypeProposal::new(mime::HTML, Some(0.8))?);
accept.push(MediaTypeProposal::new(mime::XML, Some(0.4))?);
accept.push(mime::PLAIN);

let mut res = Response::new(200);
let content_type = accept.negotiate(&[mime::XML])?;
content_type.apply(&mut res);

assert_eq!(res["Content-Type"], "application/xml;charset=utf-8");
