Functions

func Retry

func Retry(n uint, interval time.Duration, fn func() error) (err error)

Retry calls the `fn` and if it returns the error, retry to call `fn` after `interval` duration. The `fn` is called up to `n` times.

func WithContext

func WithContext(ctx context.Context, n uint, interval time.Duration, fn func() error) (err error)

WithContext stops retrying when the context is done.
