pub struct IfModifiedSince(_);
Expand description
If-Modified-Since
header, defined in
RFC7232
The If-Modified-Since
header field makes a GET or HEAD request
method conditional on the selected representation’s modification date
being more recent than the date provided in the field-value.
Transfer of the selected representation’s data is avoided if that
data has not changed.
ABNF
If-Modified-Since = HTTP-date

Example
use headers::IfModifiedSince;
use std::time::{Duration, SystemTime};
let time = SystemTime::now() - Duration::from_secs(60 * 60 * 24);
let if_mod = IfModifiedSince::from(time);
