Types

type ReturnError

type ReturnError struct {
	// contains filtered or unexported fields
}

ReturnError is a wrapper around sync.Once that properly handles: func() error instead of just func()

func (*ReturnError) Do

func (owe *ReturnError) Do(f func() error) error

Do provides the same functionality as sync.Once.Do(func()) but for func() error
