Types ¶

type RateState ¶

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

RateState 通过计数增长和时间间隔计算速率

func NewRateState ¶

func NewRateState(second ...float64) *RateState

NewRateState 创建速率计算器, 可选设置最小保护时间间隔, 默认 1 秒

func (*RateState) Rate ¶

func (r *RateState) Rate(count uint64) float64

Rate 计算并返回速率(每秒), 返回最近两次触达计算的请求时间间隔之间的计数增长平均速率非实时计算, 可能返回上一轮速率结果非精确计算, 当计数增长突发性很大或请求的时间间隔很长时, 速率结果与实际误差较大若需要得到相对精准的结果, 按指定时间间隔调用 Rate 函数 -1 表示计数器被重置或无效, 0 表示无变化
