Types

type Event

type Event[K comparable, D any] struct {
	// contains filtered or unexported fields
}

type EventHub

type EventHub[K comparable, D any] struct {
	// contains filtered or unexported fields
}

Example

m := New[int, int]()

fn1 := func(data int) { fmt.Println("1 call=", data) }
fn2 := func(data int) { fmt.Println("2 call=", data) }
fn3 := func(data int) { fmt.Println("3 call=", data) }
fn4 := func(data int) { fmt.Println("4 call=", data) }

m.On(1, fn1).On(2, fn2).On(3, fn3).On(4, fn4)

m.Fire(1, 1)
m.Fire(2, 2)
m.Fire(3, 3)
m.Fire(4, 4)

m.Off(2, fn2).Off(3, fn3)

m.Fire(1, 100)
m.Fire(2, 200)
m.Fire(3, 300)
m.Fire(4, 400)

Output:

1 call= 1
2 call= 2
3 call= 3
4 call= 4
1 call= 100
4 call= 400
