RateLimit

Simple, thread-safe Go rate-limiter. Inspired by Antti Huima's algorithm on http://stackoverflow.com/a/668327

Example

package main

import (
  "github.com/bsm/ratelimit"
  "log"
)

func main() {
  // Create a new rate-limiter, allowing up-to 10 calls
  // per second
  rl := ratelimit.New(10, time.Second)

  for i:=0; i<20; i++ {
    if rl.Limit() {
      fmt.Println("DOH! Over limit!")
    } else {
      fmt.Println("OK")
    }
  }
}
