retries

A simple, extensible Go retries library.

Example

Without any arguments, the retrier uses the default strategy of using exponential back-off, four retries, and retrying on all errors.

myFunc := func() error {
	return errors.New("error")
}

retrier := New(myFunc)
if err := retrier.Try(); err != nil {
	log.Println(err)
}

All of the parameters in the default strategy can also be customized.

myErr := errors.New("error")

myFunc := func() error {
	return myErr
}

retrier := New(
	myFunc,
	WithRetries(10),
	WithWhitelist(myErr),
	WithExpBackoff(2),
)
if err := retrier.Try(); err != nil {
	log.Println(err)
}
