Module backoff 

Exponential backoff for use with QCS.

This re-exports types from backoff and provides a default_backoff function to create a more useful default [ExpontentialBackoff].

Modules

backoff

default

Constants for the exponential backoff policy.

exponential

future

Structs

SystemClock

SystemClock uses the system’s clock to get the current time. This Clock should be used for real use-cases.

Enums

Error

Error is the error value in an operation’s result.

Traits

Clock

Clock returns the current time.

Notify

Notify is called in retry_notify in case of errors.

Functions

default_backoff

Create a default ExponentialBackoff for use with QCS.

duration_from_io_error

Return Some if the error is one that makes sense to retry and method is one that indicates it is safe to retry.

duration_from_reqwest_error

Return Some if the error is one that makes sense to retry and method is one that indicates it is safe to retry.

duration_from_response

Return Some if the response specifies a Retry-After header or the provided backoff has another backoff to try. If None is returned, the request should not be retried.

retry

Retries this operation according to the backoff policy. backoff is reset before it is used.

retry_notify

Retries this operation according to the backoff policy. Calls notify on failed attempts (in case of transient errors). backoff is reset before it is used.

status_code_is_retry

Return true if the status code is one that could be retried.

Type Aliases

ExponentialBackoff

Exponential backoff policy with system’s clock.

ExponentialBackoffBuilder

Builder for exponential backoff policy with system’s clock.
