 rust-analyzer highlights the code semantically.
 For example, `bar` in `foo::Bar` might be colored differently depending on whether `Bar` is an enum or a trait.
 rust-analyzer does not specify colors directly, instead it assigns tag (like `struct`) and a set of modifiers (like `declaration`) to each token.
