Module qcs_api_client_common::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.
• 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.
