Create a new data structure that generates a different type of generic data

I'm struggling to find the right words, so I'll provide an illustration:

// For observables
type UnwrappedObs<T> = T extends Observable<infer T> ? T : never;
// For promises
type UnwrappedPro<T> = T extends PromiseLike<infer T> ? T : never;

// How can I define GenericClass to accommodate any generic type?
type UnwrappedAll<T> = T extends GenericClass<infer T> ? T : never;

Is there a way to declare GenericClass so it can accept various generics like 

Observable | Promise | Pick | Omit | Partial | ...
?

Answer №1

Unwrapping items is not allowed due to the structural nature of TypeScript types. Unfortunately, it is impossible to accomplish what you are trying to do.
