/**
Create a deep version of another object type where property values are recursively replaced into a given value type.
Use-cases:
- Form validation: Define how each field should be validated.
- Form settings: Define configuration for input fields.
- Parsing: Define types that specify special behavior for specific fields.
@example
```
import type {Schema} from 'type-fest';
interface User {
id: string;
name: {
firstname: string;
lastname: string;
};
created: Date;
active: boolean;
passwordHash: string;
}
type UserMask = Schema<User, 'mask' | 'hide' | 'show'>;
const userMaskSettings: UserMask = {
id: 'show',
name: {
firstname: 'show',
lastname: 'mask',
},
phoneNumbers: 'mask',
created: 'show',
active: 'show',
passwordHash: 'hide',
}
```
