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: resolved_mod_ref.go
    path of file: ./repos/steampipe/pkg/modinstaller
    
    the code of the file until where you have to start completion: package modinstaller

import (
	"github.com/Masterminds/semver/v3"
	"github.com/go-git/go-git/v5/plumbing"
	"github.com/turbot/steampipe/pkg/steampipeconfig/modconfig"
	"github.com/turbot/steampipe/pkg/versionhelpers"
)

// ResolvedModRef is a struct to represent a resolved mod git reference
type ResolvedModRef struct {
	// the FQN of the mod - also the Git URL of the mod repo
	Na
    
func NewResolvedModRef(requiredModVersion *modconfig.ModVersionConstraint, version *semver.Version) (*ResolvedModRef, error) {
	res := &ResolvedModRef{
		Name:       requiredModVersion.Name,
		Version:    version,
		Constraint: requiredModVersion.Constraint,
		// this may be empty strings
		FilePath: requiredModVersion.FilePath,
	}
	if res.FilePath == "" {
		res.setGitReference()
	}

	return res, nil
