Expand description
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.

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