err := retry.Do(10, thisFunctionMayFail)
if err != nil {
  log.Fatal(err)
}

Retry with a delay.

if err != nil {
  log.Fatal(err)
}

Retry forever.

retry.DoForever(thisFunctionMayFail)

Functions

func Do

func Do(n int, f RetryFunc) (err error)

Do retries calling function f n-times. It returns an error if none of the tries succeeds.

func DoSleep

func DoSleep(n int, d time.Duration, f RetryFunc) (err error)

DoSleep retries calling function f n-times and sleeps for d after each call. It returns an error if none of the tries succeeds.

func Forever

func Forever(f RetryFunc)

Forever keeps trying to call function f until it succeeds.

func ForeverSleep

func ForeverSleep(d time.Duration, f RetryFunc)

ForeverSleep keeps trying to call function f until it succeeds, and sleeps after each failure.
