Types ¶
type NextDelay ¶
type NextDelay func(attempts int) time.Duration
NextDelay returns the amount of time to wait before the next retry given the number of attempts.

// Operation is the function to invoke.

}
A Waiter keeps retrying the specified operation until it returns true, or an error.
func (*Waiter) Wait ¶
func (w *Waiter) Wait(ctx context.Context) error
Wait waits for the specified operation to complete.
func (*Waiter) WaitWithTimeout ¶
