pub struct AccessControlAllowOrigin(_);

Expand description

The Access-Control-Allow-Origin response header, part of CORS

The Access-Control-Allow-Origin header indicates whether a resource can be shared based by returning the value of the Origin request header, *, or null in the response.

ABNF

Access-Control-Allow-Origin = "Access-Control-Allow-Origin" ":" origin-list-or-null | "*"

Example values

null

Examples

use headers::AccessControlAllowOrigin;
use std::convert::TryFrom;

let any_origin = AccessControlAllowOrigin::ANY;
let null_origin = AccessControlAllowOrigin::NULL;
let origin = AccessControlAllowOrigin::try_from("http://web-platform.test:8000");
