RequiredKeys always returns never #306

Closed Arlen22 closed 4 years ago

Required keys should be 

export type RequiredKeys<V> = { [K in keyof V]-?:
    Exclude<V[K], undefined> extends Requireable<infer T> ? never
    : Exclude<V[K], undefined> extends Validator<infer T> ? K
    : never }[keyof V];

This is a TypeScript type. This repo does not contain any TS types; you'll want to file an issue in DefinitelyTyped instead.
