Functions ¶

func Backoff ¶

func Backoff(d time.Duration) time.Duration

func Do ¶

func Do(ctx context.Context, retryableFunc RetryableFunc, opts ...Option) error

func Jitter ¶

func Jitter(d time.Duration) time.Duration

Types ¶

type AfterFunc ¶

type AfterFunc func(time.Duration) <-chan time.Time

Function signature of time.After function

type Config ¶

type Config struct {
	// contains filtered or unexported fields
}

type DynamicAttemptsFunc ¶

type DynamicAttemptsFunc func(attempt uint, attempts uint, err error) uint

Function signature of "dynamic attempts" function

type DynamicDelayFunc ¶

type DynamicDelayFunc func(attempt uint, delay time.Duration, err error) time.Duration

Function signature of "dynamic delay" function

type OnRetryFunc ¶

type OnRetryFunc func(attempt uint, err error) error

Function signature of "on retry" function

type Option ¶

type Option func(*Config)

Option represents an option for retry.

func Attempts ¶

func Attempts(attempts uint) Option

Attempts set count of retry. Setting to 0 will retry until the retried function succeeds. Default is 1 (one attampt) Number of attempts can be override by the dynamicAttempts function

func Delay ¶

func Delay(delay time.Duration) Option

Delay set delay between retry. It can be override by the delayType function Default is 0 (no delay) Number of attempts can be override by the dynamicDelay function

func DynamicAttempts ¶

func DynamicAttempts(dynamicAttempts DynamicAttemptsFunc) Option

DynamicAttempts dynamically set the number of attempts

func DynamicDelay ¶

func DynamicDelay(dynamicDelay DynamicDelayFunc) Option

DynamicDelay dynamically set the delay between retries

func OnRetry ¶

func OnRetry(onRetry OnRetryFunc) Option

OnRetry function callback are called each retry

func RetryIf ¶

func RetryIf(retryIf RetryIfFunc) Option

RetryIf controls whether a retry should be attempted after an error (assuming there are any retry attempts remaining)

func WithAfter ¶

func WithAfter(after AfterFunc) Option

WithAfter provides a way to swap out time.After implementations. This primarily is useful for mocking/testing, where you may not want to explicitly wait for a set duration for retries.

type RetryIfFunc ¶

type RetryIfFunc func(attempt uint, err error) bool

Function signature of "retry if" function

type RetryableFunc ¶

type RetryableFunc func() error

Function signature of retryable function
