bug: Error in (seemingly?) correct Rust file

[HiPhish]

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)

Describe the bug

Neovim user and maintainer of HiPhish/rainbow-delimiters.nvim here. I have a Rust file and Neovim reports four errors.

I don't know much about Rust, so maybe the code is invalid? The code itself does not make much sense, it's just a test file for trying out the rainbow delimiter highlighting. See also this PR and this issue:

• https://github.com/HiPhish/rainbow-delimiters.nvim/pull/122 (the author of the PR knows more about Rust than me)
• https://github.com/neovim/neovim/issues/29726

Steps To Reproduce/Bad Parse Tree

The offending source code is

fn main() {
    let nested_macro = vec![vec![vec![vec![vec![0]]]]];
}

The resulting tree is

(source_file ; [0, 0] - [3, 0]
  (function_item ; [0, 0] - [2, 1]
    name: (identifier) ; [0, 3] - [0, 7]
    parameters: (parameters) ; [0, 7] - [0, 9]
    body: (block ; [0, 10] - [2, 1]
      (let_declaration ; [1, 4] - [1, 55]
        pattern: (identifier) ; [1, 8] - [1, 20]

Expected Behavior/Parse Tree

There should be no errors in the tree.

[amaanq]

parsing works correctly using the tree-sitter cli. this is an issue with injections (rust inside rust), and does not belong in this repo.

[HiPhish]

Fair enough, but where does it belong then? Neovim?

[amaanq]

probably nvim-treesitter, though it's likely unsolvable you either lose macro injections or deal with spurious parse errors
