Examples
use http_types::Response; use http_types::conditional::IfModifiedSince; use std::time::{SystemTime, Duration}; let time = SystemTime::now() + Duration::from_secs(5 * 60); let expires = IfModifiedSince::new(time); let mut res = Response::new(200); expires.apply(&mut res); let expires = IfModifiedSince::from_headers(res)?.unwrap(); // HTTP dates only have second-precision. let elapsed = time.duration_since(expires.modified())?; assert_eq!(elapsed.as_secs(), 0);
Implementations
impl IfModifiedSince
[src]
pub fn new(instant: SystemTime) -> IfModifiedSince
[src]
Create a new instance of IfModifiedSince
.
pub fn modified(&self) -> SystemTime
[src]

pub fn from_headers(
headers: impl AsRef<Headers>
) -> Result<Option<IfModifiedSince>, Error>
[src]
headers: impl AsRef<Headers>
) -> Result<Option<IfModifiedSince>, Error>
Create an instance of IfModifiedSince
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]
Get the HeaderName
.
pub fn value(&self) -> HeaderValue
[src]
