backoff

NewExponentialBackOff creates an instance of ExponentialBackOff using default values.

NewTicker returns a new Ticker containing a channel that will send the time at times specified by the BackOff argument.

Permanent wraps the given err in a *PermanentError.

Retry the operation o until it does not return error or BackOff stops.

RetryNotify calls notify function with the error and wait duration for each failed attempt before sleep.

WithContext returns a BackOffContext with context ctx ctx must not be nil.

WithMaxRetries creates a wrapper around another BackOff, which will return Stop if NextBackOff() has been called too many times since the last time Reset() was called Note: Implementation is not thread-safe.

Infinity indicates that retries will be made indefinitely.

Stop indicates that no more retries should be made for use in NextBackOff().

SystemClock implements Clock interface that uses time.Now().

ConstantBackOff is a backoff policy that always returns the same backoff delay.

ExponentialBackOff is a backoff implementation that increases the backoff period for each retry attempt using a randomization function that grows exponentially.

PermanentError signals that the operation should not be retried.

StopBackOff is a fixed backoff policy that always returns backoff.Stop for NextBackOff(), meaning that the operation should never be retried.

Ticker holds a channel that delivers `ticks' of a clock at times reported by a BackOff.

ZeroBackOff is a fixed backoff policy whose backoff time is always zero, meaning that the operation is retried immediately without waiting, indefinitely.

BackOff is a backoff policy for retrying an operation.

BackOffContext is a backoff policy that stops retrying after the context is canceled.

Clock is an interface that returns current time for BackOff.

Notify is a notify-on-error function.

An Operation is executing by Retry() or RetryNotify().
