[−][src]Struct tide::http::cache::CacheControl
A Cache-Control header.
Examples
use http_types::Response; use http_types::cache::{CacheControl, CacheDirective}; let mut entries = CacheControl::new(); entries.push(CacheDirective::Immutable); entries.push(CacheDirective::NoStore); let mut res = Response::new(200); entries.apply(&mut res); let entries = CacheControl::from_headers(res)?.unwrap(); let mut entries = entries.iter(); assert_eq!(entries.next().unwrap(), &CacheDirective::Immutable); assert_eq!(entries.next().unwrap(), &CacheDirective::NoStore);
Implementations
impl CacheControl
