为什么在过滤映射键时未显示JSDOC评论？

Question

我正在尝试为类创建一个配置类型。我希望该类型将所有属性作为可选的，但没有类的功能。类似于“部分”但没有功能。我有效，但是IDE不再显示JSDOC的评论。

Here's what I have:

type Config<T> = {
                [P in keyof T as (T[P] extends Function ? never : P)]?: T[P];
            };

class Person {
                /**
                 * JSdoc must show for ID;
                 */
                public name = "";

                /**
                 * I don't want to have this one in Config
                 */
                public fn() {

                }
            }

            const config: Config<Person> = {name : "test"};
            const config2 : Partial<Person> = {name: "test"};

With config2 the jsdoc hint shows but for Config it doesn't.有人知道如何使它起作用吗？

钥匙过滤器将丢失JSDOC。但是省略和选择不会！

尝试：

type Config<T> = Omit<T, {
   [P in keyof T]: T[P] extends Function ? P : never)
}[keyof T]>
