有没有办法用ruby限制一个函数在一秒钟内被调用的次数？

class RateLimiter
  def initialize(rate_limit)
    @rate_limit = rate_limit
    @tokens = 0
    @last_refill_time = Time.now
    @lock = Mutex.new
  end

  def call
    @lock.synchronize do
      refill_tokens
      if @tokens > 0
        @tokens -= 1
        true
      else
        false
      end
    end
  end

  private

  def refill_tokens
    time_since_last_refill = Time.now - @last_refill_time
    new_tokens = (time_since_last_refill * @rate_limit).to_i
    @tokens = [@tokens + new_tokens, @rate_limit].min
    @last_refill_time = Time.now
  end
end

# 使用示例
rate_limiter = RateLimiter.new(1) # 每秒限制1次调用
10.times do
  if rate_limiter.call
    puts "函数被调用"
  else
    puts "函数调用超过限制"
  end
  sleep(0.1)
end
