Struct salvo::http::headers::IfUnmodifiedSince [−][src]
pub struct IfUnmodifiedSince(_);
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.
ABNF
If-Unmodified-Since = HTTP-date

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);
