* lisp/progmodes/rust-ts-mode.el (rust-ts-mode--font-lock-settings):
Specify import queries to avoid clashing with scoped identifiers in
the code. Highlight attributes with font-lock-preprocessor-face.
* lisp/progmodes/rust-ts-mode.el (rust-ts-mode):
New treesit font-lock feature: 'assignment' (bug#61302).
(rust-ts-mode--fontify-pattern): Remove the node lookup step.
(rust-ts-mode--font-lock-settings): Update variable declaration
queries to match the 'pattern' child node right away. Add
highlights for 'assignment.
* lisp/progmodes/rust-ts-mode.el (rust-ts-mode--font-lock-settings):
Remove :override from the 'property' rules and move them above
'variable' (bug#61302).
* lisp/progmodes/rust-ts-mode.el (rust-ts-mode--font-lock-settings):
Remove the rule that highlighted scope identifier in a function call
as type. The existing rules will handle it when it does look like a
type (capitalized).
(rust-ts-mode--font-lock-settings): Change scoped_type_identifier
highlight to match similar cases. Highlight variable declarations
inside all kinds of destructuring patterns, not just function
definitions.
* lisp/progmodes/rust-ts-mode.el (rust-ts-mode--fontify-pattern):
Rename from 'rust-ts-mode--fontify-parameter'. Check the id node's
parent to avoid touching type identifiers.
* doc/emacs/display.texi (Parser-based Font Lock):
Update description of treesit-font-lock-level, moving 'property' to
level 4.
* lisp/treesit.el (treesit-font-lock-level): Likewise, in docstring.
* lisp/progmodes/c-ts-mode.el (c-ts-base-mode): Do that here.
* lisp/progmodes/cmake-ts-mode.el (cmake-ts-mode): Add a comment.
* lisp/progmodes/go-ts-mode.el (go-ts-mode): Add 'definition' to
level 1. Move 'function', 'property' and 'variable' to level 4.
(go-ts-mode--font-lock-settings): Move a bunch of existing rules
to 'definition'. Add highlighting of function parameters.
* lisp/progmodes/rust-ts-mode.el (rust-ts-mode)
(rust-ts-mode--font-lock-settings): Same. And also change "scoped
identifiers" highlights to only match capitalized names.
* lisp/treesit.el (treesit--font-lock-level-setter): Don't loop
over all the buffers if tree-sitter is not built-in, or else
initialization of defcustom will fail. (Bug#61155)
* lisp/progmodes/rust-ts-mode.el (treesit-node-parent):
* lisp/progmodes/c-ts-common.el (treesit-node-parent): Declare, to
* avoid byte-compilation warnings.
Similar to bug#60351, the angle brackets in rust-ts-mode are not
recognized as pairs when they should be. This change copies the
function used by c++-ts-mode and adapts it to rust-ts-mode.
