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: errors.go
    path of file: ./repos/faasd/vendor/github.com/xeipuuv/gojsonschema
    
    the code of the file until where you have to start completion: package gojsonschema

import (
	"bytes"
	"sync"
	"text/template"
)

var errorTemplates = errorTemplate{template.New("errors-new"), sync.RWMutex{}}

// template.Template is not thread-safe for writing, so some locking is done
// sync.RWMutex is used for efficiently locking when new templates are created
type errorTemplate struct {
	*template.Template
	sync.RWMutex
}

type (

	// FalseError. ErrorDetails: -
	FalseError stru
    
func formatErrorDescription(s string, details ErrorDetails) string {

	var tpl *template.Template
	var descrAsBuffer bytes.Buffer
	var err error

	errorTemplates.RLock()
	tpl = errorTemplates.Lookup(s)
	errorTemplates.RUnlock()

	if tpl == nil {
		errorTemplates.Lock()
		tpl = errorTemplates.New(s)

		if ErrorTemplateFuncs != nil {
			tpl.Funcs(ErrorTemplateFuncs)
		}

		tpl, err = tpl.Parse(s)
		errorTemplates.Unlock()

		if err != nil {
			return err.Error()
		}
	}

	err = tpl.Execute(&descrAsBuffer, details)
	if err != nil {
		return err.Error()
	}

	return descrAsBuffer.String()
}
