Enum saphir::header::RetryAfter

pub enum RetryAfter {
    Delay(Duration),
    DateTime(HttpDate),
}

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;
use hyperx::header::{Headers, RetryAfter};

let mut headers = Headers::new();
headers.set(
    RetryAfter::Delay(Duration::from_secs(300))
);

use std::time::{SystemTime, Duration};
use hyperx::header::{Headers, RetryAfter};

let mut headers = Headers::new();
let date = SystemTime::now() + Duration::from_secs(300);
headers.set(
    RetryAfter::DateTime(date.into())
);

Retry-After header, defined in RFC7231

Variants

Delay(Duration)

Retry after this duration has elapsed

This can be coupled with a response time header to produce a DateTime.

DateTime(HttpDate)

Retry after the given DateTime

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 Display for RetryAfter

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

Formats the value using the given formatter.

impl PartialEq<RetryAfter> 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.
