Struct IfModifiedSince

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.

ABNF

If-Unmodified-Since = HTTP-date

Example

use hyper::header::{Headers, IfModifiedSince};
use std::time::{SystemTime, Duration};

let mut headers = Headers::new();
let modified = SystemTime::now() - Duration::from_secs(60 * 60 * 24);
headers.set(IfModifiedSince(modified.into()));

Trait Implementations

impl Clone for IfModifiedSince

fn clone(&self) -> IfModifiedSince

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IfModifiedSince

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

Formats the value using the given formatter.

impl Deref for IfModifiedSince

type Target = HttpDate

The resulting type after dereferencing.

fn deref(&self) -> &HttpDate

Dereferences the value.

impl DerefMut for IfModifiedSince

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

Mutably dereferences the value.

impl Display for IfModifiedSince

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

Formats the value using the given formatter.

impl Header for IfModifiedSince

fn header_name() -> &'static str

Returns the name of the header field this belongs to.

fn parse_header(raw: &Raw) -> Result<Self>

Parse a header from a raw stream of bytes.

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

Format a header to outgoing stream.

impl PartialEq for IfModifiedSince

fn eq(&self, other: &IfModifiedSince) -> 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.
