Struct CacheControl

pub struct CacheControl { /* private fields */ }

A Cache-Control header.

Examples

use http_types_rs::Response;
use http_types_rs::cache::{CacheControl, CacheDirective};
let mut entries = CacheControl::new();
entries.push(CacheDirective::Immutable);
entries.push(CacheDirective::NoStore);

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

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

pub fn new() -> Self

Create a new instance of CacheControl.

pub fn from_headers(headers: impl AsRef<Headers>) -> Result<Option<Self>>

Create a new instance from headers.

pub fn push(&mut self, directive: CacheDirective)

Push a directive into the list of entries.

pub fn iter(&self) -> Iter<'_>

An iterator visiting all server entries.

pub fn iter_mut(&mut self) -> IterMut<'_>

An iterator visiting all server entries.
