type Closer

type Closer interface {
	Start(ctx context.Context) context.Context
	Done()
	Close() error
}

A Closer allows you to close goroutines spawned by the owner via a derived cancellable context.

Basic example:

var owner.closer = NewCloser()
func (o *owner) startWork(ctx context.Context) {
	ctx = o.closer.Start(ctx)
	go func() {
		doWork(ctx)
		s.closer.Done()
	}
}
func (o *owner) Close() error {
	return o.closer.Close()
}
