Struct headers::Expires

pub struct Expires(/* private fields */);

Expires header, defined in RFC7234

The Expires header field gives the date/time after which the response is considered stale.

The presence of an Expires field does not imply that the original resource will change or cease to exist at, before, or after that time.

ABNF

Expires = HTTP-date

Example values

• Thu, 01 Dec 1994 16:00:00 GMT

Example

use headers::Expires;
use std::time::{SystemTime, Duration};

let time = SystemTime::now() + Duration::from_secs(60 * 60 * 24);
let expires = Expires::from(time);

Trait Implementations

impl Clone for Expires

fn clone(&self) -> Expires

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Expires

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

Formats the value using the given formatter.

impl From<Expires> for SystemTime

fn from(date: Expires) -> SystemTime

Converts to this type from the input type.

impl From<SystemTime> for Expires

fn from(time: SystemTime) -> Expires

Converts to this type from the input type.

impl Hash for Expires

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Header for Expires

fn name() -> &'static HeaderName

The name of this header.

fn decode<'i, I>(values: &mut I) -> Result<Self, Error>

where I: Iterator<Item = &'i HeaderValue>,

Decode this type from an iterator of HeaderValues.

fn encode<E: Extend<HeaderValue>>(&self, values: &mut E)

Encode this type to a HeaderMap.

impl Ord for Expires

fn cmp(&self, other: &Expires) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Expires

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Expires

fn partial_cmp(&self, other: &Expires) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
