multierror

type Builder ¶ added in v0.0.11

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

Builder captures errors from parallel goroutines.

Example usage:

var (
	errs = multierror.NewBuilder(3)
	wg   sync.WaitGroup
)
for _, foo := range foos {
	wg.Add(1)
	go func() {
		defer wg.Done()
		errs.Add(someWork(foo))
	}()
}
wg.Wait()
if err := errs.Err(); err != nil {
	// handle err
}

func NewBuilder(max int) *Builder

func (b *Builder) Add(err error)

func (b *Builder) Err() error
