 rust-ts-mode lost all color
Date: Sun, 20 Apr 2025 15:19:20 +0800
Oh! In the reproduce step, I write a typo, the bug can be reproduced by 
setting different `treesit-font-lock-level`, wen 
`treesit-font-lock-level` is 3, all colors are good, when 
treesit-font-lock-level is 4, all colors are lost.
To reproduce this: use this rust file:

Then eval:
1. (progn  (setq treesit-font-lock-level 4) (revert-buffer))
all color are lost.

2. (progn  (setq treesit-font-lock-level 3) (revert-buffer))
colors are good. !Important, level 3 is good, but level 4 lost colors.

3. (progn  (setq treesit-font-lock-level 4) (revert-buffer))
all color are lost again.


Can you reproduce this?

>> /// ```
>> /// #[derive(Clone)]
>> /// struct MyStruct<T>(T);
>> ///
>> /// impl<T: Copy> Copy for MyStruct<T> { }
>> /// ```
>> ///

>> copied regardless of /// whether `T` is `Copy`. Likewise, a generic struct
>> containing markers such as [`PhantomData`] /// could potentially be
>> duplicated with a bit-wise copy.
>> ///
>> /// ## What's the difference between `Copy` and `Clone`?
>> ///
>> /// Copies happen implicitly, for example as part of an assignment `y = x`.
>> The behavior of /// `Copy` is not overloadable; it is always a simple
>> bit-wise copy. ///
>> /// Cloning is an explicit action, `x.clone()`. The implementation of
>> [`Clone`] can /// provide any type-specific behavior necessary to duplicate
>> values safely. For example, /// the implementation of [`Clone`] for
>> [`String`] needs to copy the pointed-to string /// buffer in the heap. A
>> simple bitwise copy of [`String`] values would merely copy the /// pointer,
>> leading to a double free down the line. For this reason, [`String`] is
>> [`Clone`] /// but not `Copy`.
>> ///
>> /// [`Clone`] is a supertrait of `Copy`, so everything which is `Copy` must
>> also implement /// [`Clone`]. If a type is `Copy` then its [`Clone`]
>> implementation only needs to return `*self` /// (see the example above).
>> ///
>> /// ## When can my type be `Copy`?
>> ///
>> /// A type can implement `Copy` if all of its components implement `Copy`.
>> For example, this /// struct can be `Copy`:
>> ///
>> /// ```
>> /// # #[allow(dead_code)]
>> /// #[derive(Copy, Clone)]
>> /// struct Point {
>> ///    x: i32,
>> ///    y: i32,
>> /// }
>> /// ```
>> ///
>> /// A struct can be `Copy`, and [`i32`] is `Copy`, therefore `Point` is
>> eligible to be `Copy`. /// By contrast, consider
>> ///
>> /// ```
>> /// # #![allow(dead_code)]
>> /// # struct Point;
>> /// struct PointList {
>> ///     points: Vec<Point>,
>> /// }
>> /// ```
>> ///
>> /// The struct `PointList` cannot implement `Copy`, because [`Vec<T>`] is
>> not `Copy`. If we /// attempt to derive a `Copy` implementation, we'll get
>> an error: ///
>> /// ```text
>> /// the trait `Copy` cannot be implemented for this type; field `points`
>> does not implement `Copy` /// ```
>> ///
>> /// Shared references (`&T`) are also `Copy`, so a type can be `Copy`, even
>> when it holds /// shared references of types `T` that are *not* `Copy`.
>> Consider the following struct, /// which can implement `Copy`, because it

>> ///     point_list_ref: &'a PointList,
>> /// }
>> /// ```
>> ///
>> /// ## When *can't* my type be `Copy`?
>> ///
>> /// Some types can't be copied safely. For example, copying `&mut T` would

>> /// `Slice` struct contained a reference `&'a T`:
>> ///
>> /// ```
>> /// use std::marker::PhantomData;
>> ///
>> /// # #[allow(dead_code)]

>> ///     start: *const T,
>> ///     end: *const T,
>> ///     phantom: PhantomData<&'a T>,

>> /// ```
>> ///
>> /// This also in turn infers the lifetime bound `T: 'a`, indicating
>> /// that any references in `T` are valid over the lifetime `'a`.
>> ///
>> /// When initializing a `Slice` you simply provide the value

>> ///
