Javascript 有没有办法在typescript上用util.promisify继承方法签名？

从v8.0.0节点提供API。现在我尝试将一些回调样式的方法转换为异步/等待样式。 在typescript上，

util.promisify（）

不能继承方法签名：

import fs = require('fs');

export namespace AsyncFs {
    export const lstat = util.promisify(fs.lstat);
    // there's no method signature, only shows as "Function"
}

虽然我们可以为每个方法添加新签名

export const lstat = util.promisify(fs.lstat) as (path: string | Buffer) => fs.Stats;

所以我正在寻找一种自动继承签名的好方法。可能吗？你有什么好主意吗

谢谢。

如果不是由TS内部处理，那么您可能必须为

util.promisify（）

自己定义类型，执行类似的操作

staticpromisify（func:（回调：（err:any，result:T）=>void）=>void，options？：Bluebird.PromisifyOptions:（）=>Bluebird；
静态promisify（func:（arg1:A1，回调:（err:any，result:T）=>void）=>void，options？：Bluebird.PromisifyOptions:（arg1:A1）=>Bluebird；
静态promisify（func:（arg1:A1，arg2:A2，callback:（err:any，result:T）=>void）=>void，options？：Bluebird.PromisifyOptions:（arg1:A1，arg2:A2）=>Bluebird；
静态promisify（func:（arg1:A1，arg2:A2，arg3:A3，回调:（err:any，result:T）=>void）=>void，options？：Bluebird.PromisifyOptions:（arg1:A1，arg2:A2，arg3:A3）=>Bluebird；
静态promisify（func:（arg1:A1，arg2:A2，arg3:A3，arg4:A4，回调：（err:any，result:T）=>void）=>void，选项？：Bluebird.PromisifyOptions:（arg1:A1，arg2:A2，arg3:A3，arg4:A4）=>Bluebird；
静态promisify（函数：（arg1:A1，arg2:A2，arg3:A3，arg4:A4，arg5:A5，回调：（err:any，result:T）=>void）=>void，options？：Bluebird.PromisifyOptions:（arg1:A1，arg2:A2，arg3:A3，arg4:A4，arg5:A5）=>Bluebird；

你说的“继承”是指推断？

  static promisify<T>(func: (callback: (err: any, result: T) => void) => void, options?: Bluebird.PromisifyOptions): () => Bluebird<T>;
  static promisify<T, A1>(func: (arg1: A1, callback: (err: any, result: T) => void) => void, options?: Bluebird.PromisifyOptions): (arg1: A1) => Bluebird<T>;
  static promisify<T, A1, A2>(func: (arg1: A1, arg2: A2, callback: (err: any, result: T) => void) => void, options?: Bluebird.PromisifyOptions): (arg1: A1, arg2: A2) => Bluebird<T>;
  static promisify<T, A1, A2, A3>(func: (arg1: A1, arg2: A2, arg3: A3, callback: (err: any, result: T) => void) => void, options?: Bluebird.PromisifyOptions): (arg1: A1, arg2: A2, arg3: A3) => Bluebird<T>;
  static promisify<T, A1, A2, A3, A4>(func: (arg1: A1, arg2: A2, arg3: A3, arg4: A4, callback: (err: any, result: T) => void) => void, options?: Bluebird.PromisifyOptions): (arg1: A1, arg2: A2, arg3: A3, arg4: A4) => Bluebird<T>;
  static promisify<T, A1, A2, A3, A4, A5>(func: (arg1: A1, arg2: A2, arg3: A3, arg4: A4, arg5: A5, callback: (err: any, result: T) => void) => void, options?: Bluebird.PromisifyOptions): (arg1: A1, arg2: A2, arg3: A3, arg4: A4, arg5: A5) => Bluebird<T>;
