Typescript 通用 通用

不确定我想要什么打字稿功能，但我认为我需要一个通用的泛型（如果这是打字稿功能）。以下是我的要求。

我想表示事件/事件处理程序元组的集合。以下是我到目前为止所拥有的。

interface Event {
 type: string;
}

type EventType<T extends Event> = T['type'];
type EventHandler<T extends Event> = (event:T): void;

// so far so good
type EventTypeAndHandlerTuple <T extends Event> = [EventType<T>, EventHandler<T>];


// this is where I wish I could do better. I am forced to used any
type EventTypeAndHandlerTuples = EventTypeAndHandlerTuple<any>[]

我的希望是能够表示这样的代码

const todoAddedEvent: TodoAddedEvent = {...}
const handleTodoAddedEvent: TodoAddedHandler = (event: TodoAddedEvent) => {...};
const todoRemovedEvent: TodoRemovedEvent = {...}
const handleTodoRemovedEvent: TodoRemovedHandler = (event: TodoRemovedEvent) => {...}

// HELP ME GIVE THIS THING A TYPE
