pub struct IfModifiedSince(pub HttpDate);
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.
If-Unmodified-Since = HTTP-date
