Enum hyper::header::RetryAfter
[−]
[src]
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 hyper::header::{Headers, RetryAfter}; let mut headers = Headers::new(); headers.set( RetryAfter::Delay(Duration::from_secs(300)) );
use std::time::{SystemTime, Duration}; use hyper::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
