Generic options?

[hahanein]

Is there a way to make options generic and take the return value type as a type parameter?

I have a custom mutator defined like this:

function async mutator<Data>(config: RequestConfig, options?: Options<Data>): Promise<TypedResponse<Data, StandardError>>;

So options depends on the return value type. However, the produced functions will just convert options to Options<unknown>. For example:

export const getFoo = (options?: SecondParameter<typeof getFooMutator>) => {
	return getFooMutator<Bar>({url: `/api/foo`, method: 'GET'}, options);
};

What I really need is something like this (note the additional type parameter in the options definition)..

export const getFoo = (options?: SecondParameter<typeof getFooMutator<Bar>>) => {
	return getFooMutator<Bar>({url: `/api/foo`, method: 'GET'}, options);
};

Fixed in this issue.
