Struct poem::web::headers::RetryAfter

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

The Retry-After header.

The Retry-After response-header field can be used with a 503 (Service Unavailable) response to indicate how long the service is expected to be unavailable to the requesting client. This field MAY also be used with any 3xx (Redirection) response to indicate the minimum time the user-agent is asked wait before issuing the redirected request. The value of this field can be either an HTTP-date or an integer number of seconds (in decimal) after the time of the response.

Examples

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

let delay = RetryAfter::delay(Duration::from_secs(300));
let date = RetryAfter::date(SystemTime::now());

Retry-After header, defined in RFC7231

Implementations

impl RetryAfter

pub fn date(time: SystemTime) -> RetryAfter

Create an RetryAfter header with a date value.

pub fn delay(dur: Duration) -> RetryAfter

Create an RetryAfter header with a date value.

Trait Implementations

impl Clone for RetryAfter

fn clone(&self) -> RetryAfter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RetryAfter

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

Formats the value using the given formatter.

impl Header for RetryAfter

fn name() -> &'static HeaderName

The name of this header.

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

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

Decode this type from an iterator of HeaderValues.

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

where E: Extend<HeaderValue>,

Encode this type to a HeaderMap.

impl PartialEq for RetryAfter

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