Struct http_types::cache::Age

pub struct Age { /* fields omitted */ }

HTTP Age header

Specifications

• RFC 7234, section 5.1: Age

Examples

use http_types::Response;
use http_types::cache::Age;

let age = Age::from_secs(12);

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

let age = Age::from_headers(res)?.unwrap();
assert_eq!(age, Age::from_secs(12));

Implementations

impl Age

pub fn new(dur: Duration) -> Self

Create a new instance of Age.

pub fn from_secs(secs: u64) -> Self

Create a new instance of Age from secs.

pub fn duration(&self) -> Duration

Get the duration from the header.

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

Create an instance of Age 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 Age

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

Formats the value using the given formatter.

impl Eq for Age

impl Ord for Age

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

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Age> for Age

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

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

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

This method tests for !=.

impl PartialOrd<Age> for Age

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

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

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

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

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

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

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

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

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

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

impl StructuralEq for Age

impl StructuralPartialEq for Age

impl ToHeaderValues for Age

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.
