bors 817a6a8609 Auto merge of #12966 - OleStrohm:master, r=Veykril ... feat: Display the value of enum variant on hover fixes #12955 This PR adds const eval support for enums, as well as showing their value on hover, just as consts currently have. I developed these two things at the same time, but I've realized now that they are separate. However since the hover is just a 10 line change (not including tests), I figured I may as well put them in the same PR. Though if you want them split up into "enum const eval support" and "show enum variant value on hover", I think that's reasonable too. Since this adds const eval support for enums this also allows consts that reference enums to have their values computed now too. The const evaluation itself is quite rudimentary, it doesn't keep track of the actual type of the enum, but it turns out that Rust doesn't actually either, and `E::A as u8` is valid regardless of the `repr` on `E`. It also doesn't really care about what expression the enum variant contains, it could for example be a string, despite that not being allowed, but I guess it's up to the `cargo check` diagnostics to inform of such issues anyway?		2022-09-20 14:01:16 +00:00
