Struct LastModified

pub struct LastModified { /* private fields */ }

The last modification date of a resource.

Specifications

• RFC 7232, section 2.2: Last-Modified

Examples

use http_types_rs::Response;
use http_types_rs::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);
res.insert_header(&last_modified, &last_modified);

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.

Trait Implementations

impl Debug for LastModified

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

Formats the value using the given formatter.

impl Header for LastModified

fn header_name(&self) -> HeaderName

Access the header’s name.

fn header_value(&self) -> HeaderValue

Access the header’s value.

fn apply_header<H: AsMut<Headers>>(&self, headers: H)

Insert the header name and header value into something that looks like a Headers map.

impl Ord for LastModified

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

Restrict a value to a certain interval.

impl PartialEq for LastModified

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

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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