How to determine whether a directory exists in golang

How does golang determine whether a directory exists?

The method for golang to determine whether a file or folder exists is to use os.Stat() The error value returned by the function is judged:

If the error returned is nil, it means that the file or folder exists

If the error type returned is os.IsNotExist()Judged to be true, indicating that the file or folder does not exist

If the error returned is of other types, it is not sure whether it exists

func PathExists(path string) (bool, error) {
    _, err := os.Stat(path)
    if err == nil {
        return true, nil
    }
    if os.IsNotExist(err) {
        return false, nil
    }
    return false, err
}
