    // DefaultTimeout the default timeout for the entire retry operation
    DefaultTimeout = time.Second * 30

    // DefaultDelay the default delay between successive retry attempts
    DefaultDelay = time.Millisecond * 10

    // DefaultConverge the default converge, requiring something to succeed one time
    DefaultConverge = 1
)

func Do Uses

❖
func Do(fn RetriableFunc, options ...Option) (interface{}, error)

Do retries the given function, until there is a timeout, or until the function indicates that it has completed.

func UntilSuccess Uses

❖
func UntilSuccess(fn func() error, options ...Option) error

UntilSuccess retries the given function until success, timeout, or until the passed-in function returns nil.

func UntilSuccessOrFail Uses

❖
func UntilSuccessOrFail(t test.Failer, fn func() error, options ...Option)

UntilSuccessOrFail calls UntilSuccess, and fails t with Fatalf if it ends up returning an error

type Option Uses

❖
type Option func(cfg *config)

Option for a retry opteration.

func Converge Uses

❖
func Converge(successes int) Option

func Delay Uses

❖
func Delay(delay time.Duration) Option

Delay sets the delay between successive retry attempts.

func Timeout Uses

❖
func Timeout(timeout time.Duration) Option

Timeout sets the timeout for the entire retry operation.

type RetriableFunc Uses

❖
type RetriableFunc func() (result interface{}, completed bool, err error)
