package container/ring
Do calls function f (1st parameter) on each element of the ring, in forward order. The behavior of Do is undefined if f changes *r. (see http://golang.org/pkg/container/ring/#Ring.Do)
Golang container/ring.Ring.Do() function usage example
package main
import (
"container/ring"
"fmt"
)
func main() {
r := ring.New(10)
i := 0
f := func(v interface{}) {
v = i
i++
fmt.Printf("%d\n", v)
}
r.Do(f)
}
Output :
