-/**
-Create a type that makes the given keys required. The remaining keys are kept as is. The sister of the `SetOptional` type.
-
-Use-case: You want to define a single model where the only thing that changes is whether or not some of the keys are required.
-
-@example
-```
-import {SetRequired} from 'type-fest';
-
-type Foo = {
- a?: number;
- b: string;
- c?: boolean;
-}
-
-type SomeRequired = SetRequired<Foo, 'b' | 'c'>;
-// type SomeRequired = {
-// a?: number;
-// b: string; // Was already required and still is.
-// c: boolean; // Is now required.
-// }
-```

-export type SetRequired<BaseType, Keys extends keyof BaseType = keyof BaseType> =
- // Pick just the keys that are not required from the base type.
- Pick<BaseType, Exclude<keyof BaseType, Keys>> &
- // Pick the keys that should be required from the base type and make them required.
- Required<Pick<BaseType, Keys>> extends
- // If `InferredType` extends the previous, then for each key, use the inferred type key.
