html/template: How to bind nested structs from form data?

例の c.Bind 呼び出しから始め、リポジトリがリクエストフォームのパースとネストされた値をどのように処理しているかを調べてください。その動作を標準ライブラリのフォームデータに関する規約と比較し、想定される命名規約がサポートされているかどうか、またその結果がドキュメント化または範囲を限定した機能提案を必要とするかどうかを判断してください。

I'm trying to bind form data to nested structs, but I'm not sure if I'm doing it correctly. Is there a recommended way to handle form binding with nested structs using the standard library?

My Use Case
I have a form structure with nested fields that I want to bind to corresponding nested structs:

type UserInfo struct {
    Name string   `form:"name"`
    Sex string   `form:"sex"`
}

type UserGroup struct {
    Men []UserInfo `form:"men"`
    Women   []UserInfo `form:"women"`
}

type UserResults struct {
    Win          UserGroup `form:"win"`
    Lose UserGroup `form:"lose"`
}

func handler(w http.ResponseWriter, r *http.Request) {
    form := &UserResults{}
    if err := c.Bind(form); err != nil {
	// error handle
    }
    // Values are not bound to nested structs
}

What I've Tried
I've attempted to use dot notation in the form field names:

<form method="POST">
    <input type="number" name="win.men[0].name" value="john">
    <input type="number" name="win.men[0].sex" value="1">
</form>

Questions

1. Is there a built-in way to handle nested struct binding with the standard library?
2. If yes, what is the correct naming convention for form fields?
3. Is there any documentation I might have missed about this topic?

Environment

• Go version: 1.22

Any guidance or best practices would be greatly appreciated. If this functionality isn't currently supported, would it be worth considering as a feature request?
