You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: target.go
    path of file: ./repos/shellhub/ssh/pkg/target
    
    the code of the file until where you have to start completion: package target

import (
	"errors"
	"strings"
)

var (
	ErrSplitTarget = errors.New("could not split the target into two parts")
	ErrNotSSHID    = err
    
func (t *Target) SplitSSHID() (string, string, error) {
	if !t.IsSSHID() {
		return "", "", ErrNotSSHID
	}

	const NAMESPACE = 0
	const HOSTNAME = 1

	parts := strings.SplitN(t.Data, ".", 2)
	if len(parts) != 2 {
		return "", "", ErrSplitTarget
	}

	return parts[NAMESPACE], parts[HOSTNAME], nil
}
