Struct http_types::cache::Expires[−][src]

pub struct Expires { /* fields omitted */ }

HTTP Expires header

Specifications

RFC 7234, section 5.3: Expires

Examples

use http_types::Response;
use http_types::cache::Expires;
use std::time::{SystemTime, Duration};

let time = SystemTime::now() + Duration::from_secs(5 * 60);
let expires = Expires::new_at(time);

let mut res = Response::new(200);
expires.apply(&mut res);

let expires = Expires::from_headers(res)?.unwrap();

// HTTP dates only have second-precision.
let elapsed = time.duration_since(expires.expiration())?;
assert_eq!(elapsed.as_secs(), 0);

Implementations

`impl Expires`[src]

`pub fn new(dur: Duration) -> Self`[src]

`pub fn expiration(&self) -> SystemTime`[src]

Get the expiration time.

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

Create an instance of Expires from a Headers instance.

`pub fn apply(&self, headers: impl AsMut<Headers>)`[src]

Insert a HeaderName + HeaderValue pair into a Headers instance.

`pub fn name(&self) -> HeaderName`[src]
