Types

type Emulator

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

Emulator is a device which you can use to simulate a slower computer's clockspeed.

func NewEmulator

func NewEmulator(hz int64) *Emulator

NewEmulator returns a new emulator based on some number of hertz

func (*Emulator) WaitForCycles

func (e *Emulator) WaitForCycles(cycles int64, waitFunc func(d time.Duration))

WaitForCycles will wait for a period of time that would allow the emulator to slow down the current thread based on its hertz. Whatever "waiting" means is up to the caller. Note that this function is not perfect; I've observed situations where the cycle rate can overclock a bit. The point is merely to get close to the correct rate.
