Struct Age

pub struct Age { /* private fields */ }

HTTP Age header

Specifications

• RFC 7234, section 5.1: Age

Examples

use http_types_rs::Response;
use http_types_rs::cache::Age;

let age = Age::from_secs(12);

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

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.

Trait Implementations

impl Debug for Age

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

Formats the value using the given formatter.

impl Header for Age

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 Age

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

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