Struct trillium_http_types::conditional::IfMatch

pub struct IfMatch { /* fields omitted */ }

Apply the HTTP method if the ETag matches.

Specifications

• RFC 7232, section 3.1: If-Match

Examples

use http_types::Response;
use http_types::conditional::{IfMatch, ETag};

let mut entries = IfMatch::new();
entries.push(ETag::new("0xcafebeef".to_string()));
entries.push(ETag::new("0xbeefcafe".to_string()));

let mut res = Response::new(200);
res.insert_header(&entries, &entries);

let entries = IfMatch::from_headers(res)?.unwrap();
let mut entries = entries.iter();
assert_eq!(entries.next().unwrap(), &ETag::new("0xcafebeef".to_string()));
assert_eq!(entries.next().unwrap(), &ETag::new("0xbeefcafe".to_string()));
