我正在寻找一种方法来限制let area = stroke.copy(strokingWithWidth: 15, lineCap: .round, lineJoin: .round, miterLimit: 1)
if (area.contains(point)) { ... }
上的排放，如果在指定的时间内未发出值，则不必施加延迟。
我该如何实现？有运营商这样做吗？我认为swift和js的Throttle就是这样，而不是RxPY。
Subject() from rx.subjects import Subject
from time import sleep
emitter = Subject()
def callback(item):
print(item)
emitter.throttle(5000).subscribe(callback)
emitter.on_next('This should be emitted immediately')
sleep(1)
emitter.on_next('This should be emitted in 4 seconds')
sleep(6)
emitter.on_next('This should be emitted immediately')
sleep(1)
emitter.on_next('This should be emitted in 4 seconds, but will be replaced by the last value emitted in this 5 seconds period')
emitter.on_next('This should be emitted in 4 seconds, but will be replaced by the last value emitted in this 5 seconds period')
emitter.on_next('This should be emitted in 4 seconds, but will be replaced by the last value emitted in this 5 seconds period')
emitter.on_next('This should be emitted in 4 seconds')
运算符几乎可以满足我的要求。它立即发出，但之后忽略值。如果希望在此期间什么都没发出，那么我希望立即发出一个值，并且我希望在该周期结束时得到最新的值。
