Types ¶
type Group ¶
type Group struct {
// contains filtered or unexported fields
}
Group collects actors (functions) and runs them concurrently. When one actor (function) returns, all actors are interrupted. The zero value of a Group is useful.
func (*Group) Add ¶
Add an actor (function) to the group. Each actor must be pre-emptable by an interrupt function. That is, if interrupt is invoked, execute should return. Also, it must be safe to call interrupt even after execute has returned.
The first actor (function) to return interrupts all running actors. The error is passed to the interrupt functions, and is returned by Run.
