I'm making a future proposal [Partial Types v3](https://github.com/VitWW/rfcs/blob/partial_types3/text/0000-partial_types.md)

And exists topic on Internals - [[Pre? RFC] Partial types and partial mutability](https://internals.rust-lang.org/t/pre-rfc-partial-types-and-partial-mutability/18760)

And Partial Enums looks like this:

```rust
fn f(x: SomeEnum.{Foo}) { ... }

let x: SomeEnum.{Foo} = SomeEnum::Foo(3);

```
