type Promisify<T> = T &
{
  [K in Extract<keyof T, string> as `${K}Promise`]: T[K] extends (

    mmetadata: infer Metadata,
    option: infer Option,
    callback: (_err: any, res: infer Res) => void,
  ) => void
    ? <T = Res>(req: Req, mmetadata?: Metadata, option?: Option) => Promise<T>
    : never;
};

class Service {
  method() {
    let service = 1 as Promisify<Client>;
