研究方向
The issue is in the Rust language grammar file, likely `src/languages/rust.js`. The grammar needs to handle escaped double quotes in attribute strings. The fix involves updating the pattern for strings in attributes to recognize `\"` as an escaped quote. See the existing string handling in the grammar for reference. Check the issue comments for any additional context or partial solutions.
