An example of a channel being piped into a range loop in Go.

channelRangeEx.go

package main

import (
	"fmt"
)

func main() {
	c := make(chan int)

	go func() {
		for i := 0; i < 5; i++ {
			c <- i
			fmt.Println("func loop:", i)
		}
		close(c)
	}()

	for v := range c {
		fmt.Println(v)
	}
	fmt.Println("about to exit")
}

Output:

func loop: 0
0
1
func loop: 1
func loop: 2
2
3
func loop: 3
func loop: 4
4
about to exit
