Types

type DisconnectStack

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

DisconnectStack is a stack of disconnect functions. Use it to defer disconnecting callbacks.

func (*DisconnectStack) Connect

func (d *DisconnectStack) Connect(s *Signaler, f func())

Connect connects a callback to the stack.

func (*DisconnectStack) Disconnect

func (d *DisconnectStack) Disconnect()

Disconnect disconnects all callbacks.

func (*DisconnectStack) Pop

func (d *DisconnectStack) Pop()

Pop pops a disconnect function from the stack.

func (*DisconnectStack) Push

func (d *DisconnectStack) Push(funcs ...func())

Push pushes a disconnect function to the stack.

type Signaler

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

Signaler manages signaling events to callbacks. A zero-value Signaler is ready to use.

func (*Signaler) Connect

func (s *Signaler) Connect(f func()) func()

Connect connects a callback to the signaler. The returned function disconnects the callback.

func (*Signaler) Disconnect

func (s *Signaler) Disconnect()

Disconnect disconnects all callbacks.

func (*Signaler) Signal

func (s *Signaler) Signal()
