Description
One thing I miss is for user-defined types to be assigned a highlight group, so that I can give them the same color as basic types such as i32, usize, String, etc.
By user-defined types, I mean types that you as a programmer have defined in your project/crate.
Eventually also for types imported from other crates.
If there are performance issues, maybe the plugin should update its table/index/whatever of keywords on explicit command.
