Struct headers::RetryAfter

source ·
pub struct RetryAfter(/* private fields */);
Expand description

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
