Struct 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 rama_http_headers::{RetryAfter, util::Seconds};
use rama_utils::time::now_system_time;

let delay = RetryAfter::delay(Seconds::new(300));
let date = RetryAfter::date(now_system_time());

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(seconds: Seconds) -> RetryAfter

Create an RetryAfter header with a delay value in seconds

pub fn after(&self) -> After

Trait Implementations

impl Clone for RetryAfter

fn clone(&self) -> RetryAfter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RetryAfter

impl Debug for RetryAfter

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

Formats the value using the given formatter.

impl Eq for RetryAfter

impl HeaderDecode for RetryAfter

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

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

Decode this type from an iterator of HeaderValues.

impl HeaderEncode for RetryAfter

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

where E: Extend<HeaderValue>,

Encode this type to a HeaderValue, and add it to a container which has HeaderValue type as each element.

fn encode_to_value(&self) -> Option<HeaderValue>

Encode this header to HeaderValue.

impl PartialEq for RetryAfter

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

impl TypedHeader for RetryAfter

fn name() -> &'static HeaderName

The name of this header.
