Types

type WaitGroup

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

WaitGroup is a custom sync.WaitGroup that handles functions that return errors.

func (*WaitGroup) Do

func (wg *WaitGroup) Do(fn func() error)

Do starts a new goroutine and executes the function within that goroutine. This will not execute the function if an error has already occurred.

func (*WaitGroup) Wait

func (wg *WaitGroup) Wait() error

Wait waits for all of the goroutines started with Do to finish. It returns the first error encountered, but will wait for the remaining goroutines to finish.
