Functions ¶
func EngineErrorIsFatal ¶ added in v0.3.10
func EngineErrorIsNonFatal ¶ added in v0.3.8
func IntSliceContainsInt ¶
func IntSlicesEqual ¶
func RetryFunc ¶
func RetryFunc(ctx context.Context, loggerInstance logger.Logger, attempts int, retryInterval *time.Duration, backoff *Backoff, fn func(int) (bool, error, int)) error
RetryFunc give either retryInterval or backoff gets fn func(int) (bool, error, int) as parameter which returns: bool - whether should be retried error - whether error happened int - increments retries (allows manage retries count from inside of this function)
func StringSlicesEqual ¶
func Uint64SlicesEqual ¶
Types ¶
type Backoff ¶
type Backoff struct {
// Factor is the multiplying factor for each increment step
Factor float64
// Jitter eases contention by randomizing backoff steps
Jitter bool
// Min and Max are the minimum and maximum values of the counter
Min, Max time.Duration
// contains filtered or unexported fields
}
Backoff is a time.Duration counter, starting at Min. After every call to the Duration method the current timing is multiplied by Factor, but it never exceeds Max.
Backoff is not generally concurrent-safe, but the ForAttempt method can be used concurrently.
func (*Backoff) Duration ¶
Duration returns the duration for the current attempt before incrementing the attempt counter. See ForAttempt.
func (*Backoff) ForAttempt ¶
ForAttempt returns the duration for a specific attempt. This is useful if you have a large number of independent Backoffs, but don't want use unnecessary memory storing the Backoff parameters per Backoff. The first attempt should be 0.
ForAttempt is concurrent-safe.
