带有初始化程序（工厂模式）或单个接口和方法的预编译模板，或者还有什么？

PROBLEM

I'm trying to use authboss (https://github.com/volatiletech/authboss) with quicktemplate (https://github.com/valyala/quicktemplate).

The authboss rendering system is defined by one interface: Renderer.

I have created two different versions of the solution and would like to know which one is best or if there is a third one better.

1. https://github.com/frederikhors/authbossQuicktemplate_1, with factory pattern and initializators

2. https://github.com/frederikhors/authbossQuicktemplate_2, with interface and a SetData(data authboss.HTMLData) (page PageImpl) method

QUESTIONS

I don't know what to improve for performances.

• Is it possible to do the same thing differently and less in terms of hardware resources?

• Do you think I can improve using pointers somewhere?

RELEVANT CODE

1. Solution with Factory pattern and initializators:

   type HTML struct {
     templates map[string]func(authboss.HTMLData) templates.PageImpl
   }
   
   func (h *HTML) Load(names ...string) error {
     for _, n := range names {
       switch n {
       case "login":
         h.templates[n] = InitializeLoginPage
       case "recover":
         h.templates[n] = InitializeRecoverPage
       }
     }
     return nil
   }
   
   func (h *HTML) Render(ctx context.Context, page string, data authboss.HTMLData) (output []byte, contentType string, err error) {
     buf := &bytes.Buffer{}
     tpl, ok := h.templates[page]
     if !ok {
       return nil, "", errors.Errorf("template for page %s not found", page)
     }
     templates.WritePage(buf, tpl(data))
     return buf.Bytes(), "text/html", nil
   }
   
   func InitializeLoginPage(data authboss.HTMLData) templates.PageImpl {
     return &templates.LoginPage{Data: data}
   }
   
   func InitializeRecoverPage(data authboss.HTMLData) templates.PageImpl {
     return &templates.RecoverPage{Data: data}
   }
   

2. Solution with interface with a method

   type HTML struct {
     templates map[string]templates.AuthPageImpl
   }
   
   func (h *HTML) Load(names ...string) error {
     for _, n := range names {
       switch n {
       case "login":
         h.templates[n] = &templates.LoginPage{}
       case "recover":
         h.templates[n] = &templates.RecoverPage{}
       }
     }
     return nil
   }
   
   func (h *HTML) Render(ctx context.Context, page string, data authboss.HTMLData) (output []byte, contentType string, err error) {
     buf := &bytes.Buffer{}
     tpl, ok := h.templates[page]
     if !ok {
       return nil, "", errors.Errorf("template for page %s not found", page)
     }
     template := tpl.SetData(data)
     templates.WritePage(buf, template)
     return buf.Bytes(), "text/html", nil
   }
   
   type AuthPageImpl interface {
     SetData(data authboss.HTMLData) PageImpl
   }
   
   type LoginPage struct {
     Data authboss.HTMLData
   }
   
   type RecoverPage struct {
     Data authboss.HTMLData
   }
   
   func (p *LoginPage) SetData(data authboss.HTMLData) (page PageImpl) {
     p.Data = data
     return p
   }
   
   func (p *RecoverPage) SetData(data authboss.HTMLData) PageImpl {
     p.Data = data
     return p
   }
