Functions

func BatchGoOrErr

func BatchGoOrErr(fs ...func() error) error

BatchGoOrErr starts multiple goroutines and returns the error once a goroutine stops with an error. CAUTION: Other goroutines aren't and won't be closed when a goroutine stops with an error. In other words, those still-running goroutines "leak" It is safe only when the error returned by BatchGoOrEr will eventually quit the program.
