Can we burn in the routine name here?

	// contains filtered or unexported fields
}

func NewReactor

func NewReactor(bufferSize int) *Reactor

func (*Reactor) AddPeer

func (r *Reactor) AddPeer()

func (*Reactor) Receive

func (r *Reactor) Receive(event Event)

func (*Reactor) Start

func (r *Reactor) Start()

func (*Reactor) Stop

func (r *Reactor) Stop()

type Routine

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

Routines are a structure which model a finite state machine as serialized stream of events processed by a handle function. This Routine structure handles the concurrency and messaging guarantees. Events are sent via `send` are handled by the `handle` function to produce an iterator `next()`. Calling `close()` on a routine will conclude processing of all sent events and produce `final()` event representing the terminal state.
