VSCode feature request: display enum variant attributes on hover

[Expurple]

Currently, VSCode doesn't display any attributes when I hover over an enum variant:

For me, it would be very handy to check attributes like #[error("...")] and #[serde(rename = "...")] without having to jump to the enum definition.

Is there some reason why the attributes shouldn't be displayed? Or is it a desirable but unimplemented feature?

[Veykril]

It's an interesting question. People could consider it being clutter depending on the macros used on the definition, and there are likely some that you wouldn't wanna see (example would be serdes derive helpers).

[Expurple]

Sure. I suppose, another example of noisy "clutter" attributes would be lint level overrides: allow, warn, etc.

This begs the next question: whether it's acceptable to have an opinionated list of hidden-by-default attributes, as a solution. I've never configured or contributed to rust-analyzer before, so I'm not sure how opinionated it is in general.

[Veykril]

We don't want to special case third party crates for features, a config wouldn't really make much sense here either in my opinion (I'd rather not have a weird config for this). So I am not sure how we could support this.

[Expurple]

Ok, if we do no special casing/configuration, then we're left with the choice of displaying all attributes or none of them. In my codebases, displaying everything wouldn't be too noisy (especially if we're talking about enum variants and not enums/structs themselves). But other people's codebases and tastes may be different. If you decide against the noise and close the issue, that's OK.
