bug: slow textobject select queries

aclementev commented 2 months ago

Did you check existing issues?

[X] I have read all the tree-sitter docs if it relates to using the parser
[X] I have searched the existing issues of tree-sitter-rust

Tree-Sitter CLI Version, if relevant (output of `tree-sitter --version`)

No response

Describe the bug

Opening a rust buffer with the textobject.select.enable = true option set is very slow. The time difference when opening an empty foo.rs file is very noticeable (on my setup it's around ~700ms).

Steps To Reproduce/Bad Parse Tree

Enable textobject.select treesitter plugin
Open any rust file, even an empty one: nvim foo.rs

Expected Behavior/Parse Tree

I would expect the buffer to not take a noticeable amount of time to open (<300ms or something like that)

Repro

I am familiar with the textobjects project, but I figured it would be related to this parser, since I use it with other multiple languages and this is the only one that shows this behavior

that's not a parser issue - that's a query issue
