-// .Token Modifiers
+//
+// #### Token Modifiers
//
// Token modifiers allow to style some elements in the source code more precisely.
//
// Rust-analyzer currently emits the following token modifiers:
//
-// [horizontal]
-// async:: Emitted for async functions and the `async` and `await` keywords.
-// attribute:: Emitted for tokens inside attributes.
-// callable:: Emitted for locals whose types implements one of the `Fn*` traits.
-// constant:: Emitted for consts.
-// consuming:: Emitted for locals that are being consumed when use in a function call.
-// controlFlow:: Emitted for control-flow related tokens, this includes the `?` operator.
-// crateRoot:: Emitted for crate names, like `serde` and `crate`.
-// declaration:: Emitted for names of definitions, like `foo` in `fn foo() {}`.
-// defaultLibrary:: Emitted for items from built-in crates (std, core, alloc, test and proc_macro).
-// documentation:: Emitted for documentation comments.
-// injected:: Emitted for doc-string injected highlighting like rust source blocks in documentation.
-// intraDocLink:: Emitted for intra doc links in doc-strings.
-// library:: Emitted for items that are defined outside of the current crate.
-// macro:: Emitted for tokens inside macro calls.
-// mutable:: Emitted for mutable locals and statics as well as functions taking `&mut self`.
-// public:: Emitted for items that are from the current crate and are `pub`.
-// reference:: Emitted for locals behind a reference and functions taking `self` by reference.
-// static:: Emitted for "static" functions, also known as functions that do not take a `self` param, as well as statics and consts.
-// trait:: Emitted for associated trait items.
-// unsafe:: Emitted for unsafe operations, like unsafe function calls, as well as the `unsafe` token.
