Description
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?

Research direction
Start by tracing rust-analyzer's hover handling for enum variants and how the result is rendered in VSCode. Check how existing hover information is tested, then determine how attributes such as #[error] and #[serde(rename = "...")] should appear. Done means hovering an enum variant displays its relevant attributes without navigating to the definition.
