Struct IfUnmodifiedSince

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

let mut builder = Response::Ok();
let modified = SystemTime::now() - Duration::from_secs(60 * 60 * 24);
builder.set(IfUnmodifiedSince(modified.into()));

Trait Implementations

impl Clone for IfUnmodifiedSince

fn clone(&self) -> IfUnmodifiedSince

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IfUnmodifiedSince

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl DerefMut for IfUnmodifiedSince

fn deref_mut(&mut self) -> &mut HttpDate

Mutably dereferences the value.

impl Display for IfUnmodifiedSince

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Header for IfUnmodifiedSince

fn name() -> HeaderName

Returns the name of the header field

fn parse<T>(msg: &T) -> Result<Self, ParseError>

where T: HttpMessage,

Parse a header

impl IntoHeaderValue for IfUnmodifiedSince

type Error = InvalidHeaderValue

The type returned in the event of a conversion error.

fn try_into(self) -> Result<HeaderValue, Self::Error>

Try to convert value to a Header value.

impl PartialEq for IfUnmodifiedSince

fn eq(&self, other: &IfUnmodifiedSince) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Deref for IfUnmodifiedSince

type Target = HttpDate

The resulting type after dereferencing.

fn deref(&self) -> &HttpDate

Dereferences the value.
