Types

type Group

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

func WithContext

func WithContext(ctx context.Context) (*Group, context.Context)

func (*Group) Go

func (g *Group) Go(f func() error)

Go calls the given function in a new goroutine. It blocks until the new goroutine can be added without the number of active goroutines in the group exceeding the configured limit.

The first call to return a non-nil error cancels the group's context, if the group was created by calling WithContext. The error will be returned by Wait.

func (*Group) SetLimit

func (g *Group) SetLimit(n int)

func (*Group) TryGo

func (g *Group) TryGo(f func() error) bool

func (*Group) Wait

func (g *Group) Wait() error
