easy way to unzip file with golang

Question

is there a easy way to unzip file with golang ?

right now my code is:

func Unzip(src, dest string) error {
    r, err := zip.OpenReader(src)
    if err !

package main

)

func main() {
    if err := foo("test.zip"); err != nil {
        fmt.Println(err)
    }
}

func foo(yourZipFile string) error {
    tmpDir, err := ioutil.TempDir("/tmp", "yourPrefix-")
    if err != nil {
        return err
    }
    defer os.RemoveAll(tmpDir)
    if filenames, err := Unzip(yourZipFile, tmpDir); err != nil {
