Method MakeMap

expr/types.go:598–611

MakeMap examines the key type from a Map and create a map with builtin type if possible. The idea is to avoid generating map[any]any, which cannot be handled by json.Marshal.

(raw map[any]any)

// if possible. The idea is to avoid generating map[any]any,
// which cannot be handled by json.Marshal.
func (m *Map) MakeMap(raw map[any]any) any {
	ma := reflect.MakeMap(toReflectType(m))
	keys := make([]any, 0, len(raw))
	for key := range raw {
		keys = append(keys, key)
	}
	sort.Slice(keys, func(i, j int) bool {
		return reflect.ValueOf(keys[i]).String() < reflect.ValueOf(keys[j]).String()
	})
	for _, key := range keys {
		ma.SetMapIndex(reflect.ValueOf(key), reflect.ValueOf(raw[key]))
	}
	return ma.Interface()
}

// ToMap converts a MapVal to a map.
