Is there a ~type Replace<T, R extends Partial<Record<keyof T, any>>> = Omit<T, keyof R> & R;

[SrBrahma]

What I want to to is to for example safely replace {c: number} to {c: string}. The type Replace<T, R extends Partial<Record<keyof T, any>>> = Omit<T, keyof R> & R; I have allows exactly this, but I couldn't find a type in this lib that does this, by having R extending T, so it helps me building R and keeps it type safe.

There are similar types in the lib, like

Update<O extends object, K extends Key ...
Modify<O extends object, OMod extends object>
type Overwrite<O extends object, O1 extends object>

But none of them, that I've found, have a second generic that extends the origin obj type.

This time there's no lucky 😆 I think there isn't exactly that type. Overwrite https://github.com/millsp/ts-toolbelt/blob/master/sources/Object/Overwrite.ts is the most approximated type, it only replaces with the props of R which T has.

By the way, I think it's a useful feature and it could be added, or via a third generic argument as a "configuration" to Overwrite (e.g, like deep or match in other types)
