Struct http_types::conditional::LastModified

pub struct LastModified { /* fields omitted */ }

The last modification date of a resource.

Specifications

• RFC 7232, section 2.2: Last-Modified

Examples

use http_types::Response;
use http_types::conditional::LastModified;
use std::time::{SystemTime, Duration};

let time = SystemTime::now() + Duration::from_secs(5 * 60);
let last_modified = LastModified::new(time);

let mut res = Response::new(200);
last_modified.apply(&mut res);

let last_modified = LastModified::from_headers(res)?.unwrap();

// HTTP dates only have second-precision.
let elapsed = time.duration_since(last_modified.modified())?;
assert_eq!(elapsed.as_secs(), 0);

Implementations

impl LastModified

pub fn new(instant: SystemTime) -> Self

Create a new instance of LastModified.

pub fn modified(&self) -> SystemTime

Returns the last modification time listed.

pub fn from_headers(headers: impl AsRef<Headers>) -> Result<Option<Self>>

Create an instance of LastModified from a Headers instance.

pub fn apply(&self, headers: impl AsMut<Headers>)

Insert a HeaderName + HeaderValue pair into a Headers instance.

pub fn name(&self) -> HeaderName

Get the HeaderName.

pub fn value(&self) -> HeaderValue

Get the HeaderValue.

Trait Implementations

impl Debug for LastModified

impl Eq for LastModified

impl Ord for LastModified

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

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

impl PartialEq<LastModified> for LastModified

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

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

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

This method tests for !=.

impl PartialOrd<LastModified> for LastModified

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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

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

impl StructuralEq for LastModified

impl StructuralPartialEq for LastModified

impl ToHeaderValues for LastModified

type Iter = IntoIter<HeaderValue>

Returned iterator over header values which this type may correspond to.

fn to_header_values(&self) -> Result<Self::Iter>

Converts this object to an iterator of resolved HeaderValues.
