func CalculateStartTimeMilli(curTimeMs int64, interval int64) int64

CalculateStartTimeMilli 计算起始滑窗

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

SlidingWindow 滑窗通用实现

func NewSlidingWindow(slideCount int, intervalMs int) *SlidingWindow

NewSlidingWindow 创建滑窗

func (s *SlidingWindow) AcquireCurrentValues(curTimeMs int64) (uint32, uint32, *Window)

AcquireCurrentValues 获取上报数据

func (s *SlidingWindow) AddAndGetCurrentLimited(curTimeMs int64, value uint32) (uint32, *Window)

AddAndGetCurrentLimited 原子增加，并返回当前bucket

func (s *SlidingWindow) AddAndGetCurrentPassed(curTimeMs int64, value uint32) (uint32, *Window)

AddAndGetCurrentPassed 原子增加，并返回当前bucket

func (s *SlidingWindow) TouchCurrentPassed(curTimeMs int64) (uint32, *Window)

TouchCurrentPassed 获取上报数据

type Window struct {
	// 起始时间
	WindowStart int64
	// 通过数
	PassedValue uint32
	// 被限流数
	LimitedValue uint32
}

Window 单个窗口
