iter

func N ¶

func N(n int) []struct{}

N returns a slice of n 0-sized elements, suitable for ranging over.

For example:

for i := range iter.N(10) {
    fmt.Println(i)
}

... will print 0 to 9, inclusive.

It does not cause any allocations.

package main

import (
	"fmt"

	"github.com/ipfs/go-ipfs/Godeps/_workspace/src/github.com/bradfitz/iter"
)

func main() {
	for i := range iter.N(4) {
		fmt.Println(i)
	}
}

Output:

0
1
2
3
