Simple, thread-safe Go rate-limiter. Inspired by Antti Huima's algorithm on https://stackoverflow.com/a/668327
package main
import (
"github.com/bsm/ratelimit/v3"
"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")
}
}
}
