[−][src]Struct rocket::http::hyper::header::IfUnmodifiedSince
If-Unmodified-Since
header, defined in
RFC7232
The If-Unmodified-Since
header field makes the request method
conditional on the selected representation's last modification date
being earlier than or equal to the date provided in the field-value.
This field accomplishes the same purpose as If-Match for cases where
the user agent does not have an entity-tag for the representation.
ABNF
If-Unmodified-Since = HTTP-date

Example
// extern crate time; use hyper::header::{Headers, IfUnmodifiedSince, HttpDate}; use time::{self, Duration}; let mut headers = Headers::new(); headers.set(IfUnmodifiedSince(HttpDate(time::now() - Duration::days(1))));
