NewBackoff creates a new Backoff configuration with default values (see constants).

NewErrCannotRetry wraps the given error into an ErrCannotRetry and should be used to break from a Retry() function when the retry should stop immediately.

Retry is a convenience wrapper to execute the retry with default values (see exported constants).

DefaultMaxIterations contains the default value to use for number of iterations: infinite.

DefaultMaxIterationTime contains the default value to use for maximum iteration time.

DefaultMaxTotalTime contains the default value to use for maximum execution time: infinite.

DefaultMinIterationTime contains the default value to use for initial iteration time.

DefaultMultipler contains the default multiplier to apply to iteration time after each iteration.

Backoff holds the configuration for backoff function retries.

Retryable is a function which takes no parameters and yields an error when it should be retried and nil when it was successful.
