Closing as bool is the correct type in this case

By isCancel type assert, when the function result is true, the next context typescript will treat the value is Cancel type. It will help developer to write code with code lint @jasonsaayman

The case when error has type AxiosError | Cancel, when we call axios.isCancel(err), the error value will change to type never

function test(err: AxiosError | Cancel) {
  if (axios.isCancel(err)) {
    err // AxiosError | Cancel
  } else {
    err // never
  }
}

I believe this's a bug.

My solution is remove Cancel interface and extend CanceledError

export class CanceledError<T = any> extends AxiosError<T> {
+ private __CANCEL__: true;
}

- interface Cancel {
-   message?: string;
- }
