GetBackoffForNextSchedule calculates the backoff time for the next run given a cronSchedule, workflow start time and workflow close time.

GetBackoffForNextScheduleInSeconds calculates the backoff time in seconds for the next run given a cronSchedule and current time.

IgnoreErrors can be used as IsRetryable handler for Retry function to exclude certain errors from the retry list.

JitDuration return random duration from (1-coefficient)*duration to (1+coefficient)*duration, inclusive, exclusive.

JitFloat64 return random number from (1-coefficient)*input to (1+coefficient)*input, inclusive, exclusive.

JitInt64 return random number from (1-coefficient)*input to (1+coefficient)*input, inclusive, exclusive.

New makes a new Interface.

NewConcurrentRetrier returns an instance of concurrent backoff retrier.

NewExponentialRetryPolicy returns an instance of ExponentialRetryPolicy using the provided initialInterval.

NewMultiPhasesRetryPolicy creates MultiPhasesRetryPolicy.

NewRetrier is used for creating a new instance of Retrier.

Retry function can be used to wrap any call with retry logic using the passed in policy The returned error will be preferred to a previous one if one exists.

ValidateSchedule validates a cron schedule spec.

NoBackoff is used to represent backoff when no cron backoff is needed.

NoInterval represents Maximim interval.

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

Interface does f in a loop, sleeping for initialBackoff between each iterations.
