Expand description

RetryKind describes how a request MAY be retried for a given response

A RetryKind describes how a response MAY be retried; it does not mandate retry behavior. The actual retry behavior is at the sole discretion of the RetryStrategy in place. A RetryStrategy may ignore the suggestion for a number of reasons including but not limited to:

  • Number of retry attempts exceeded
  • The required retry delay exceeds the maximum backoff configured by the client
  • No retry tokens are available due to service health

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Error(ErrorKind)

Retry the associated request due to a known ErrorKind.

§

Explicit(Duration)

An Explicit retry (e.g. from x-amz-retry-after).

Note: The specified Duration is considered a suggestion and may be replaced or ignored.

§

UnretryableFailure

The response was a failure that should not be retried.

§

Unnecessary

The response was successful, so no retry is necessary.
