Struct hyper::header::IfUnmodifiedSince [−] [src]

pub struct IfUnmodifiedSince(pub HttpDate);

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
