Slint enums lose underscores in Rust

[otiv-wannes-vanleemput]

Im using a Slint enum to control the state the UI is in. It looks like this:

export enum FooState {
    HELLO_STATE,
    HAPPY_STATE,
    SAD_STATE,
}

In Rust, the FooState enum loses the underscores, for example:

let foo_state = FooState.HAPPYSTATE

Am I missing the proper casing for enums in Slint? I'm planning to add quite a lot of states, losing the underscores hurts readability, and I don't like that my Rust names don't match the Slint names.

Enums are converted to camel case. So hello_state becomes HelloState which match the convention in rust.
In Slint the convention for enums is to use lower case snake/kebab case. So The idomatic way tyo do it would be

export enum FooState {
    hello-state,
    happy-state,
    sad-state,
}

Which would be in rust:

let foo_state = FooState::HappyState;

Admittedly, we should probably have kept the underscore when the name was in upper case. But now that would be a breaking change unfortunately. (Unless we add compiler option or attribute for this kind of configuration)

Thanks! Changing it to keep underscores probably isn't high priority for you. I'm happy to use lower snake case + camel case.
