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: gen_type_toot_hashtag.go
    path of file: ./repos/gotosocial/vendor/github.com/superseriousbusiness/activity/streams/impl/toot/type_hashtag
    
    the code of the file until where you have to start completion: // Code generated by astool. DO NOT EDIT.

package typehashtag

import (
	"fmt"
	vocab "github.com/superseriousbusiness/activity/streams/vocab
    
func (this TootHashtag) helperJSONLDContext(i jsonldContexter, toMerge map[string]string) map[string]string {
	if i == nil {
		return toMerge
	}
	for k, v := range i.JSONLDContext() {
		/*
		   Since the literal maps in this function are determined at
		   code-generation time, this loop should not overwrite an existing key with a
		   new value.
		*/
		toMerge[k] = v
	}
	return toMerge
