Rewrite Rustdoc

Ensure all Rust documentation and comments are exclusively written in English, following rustdoc guidelines.

Steps

1. Determine which files to process:

- If the user provides a method to find files, use that method. - Otherwise, assume files are in the src/ directory. - Proceed immediately to the next steps after acquiring file information.

1. Conduct a comprehensive review to ensure all documentation and comments are in English.

- Any Chinese text in documentation or code comments must be identified and corrected. - Chinese characters in test case strings are permissible and do not require modification. - Chinese report files should not be modified — focus on Rust source code files only.

1. Search for Chinese characters in the source code:

``bash rg -n "[\u4e00-\u9fff]" src/ ` Check for missing documentation: `bash cd src/ && cargo clippy -- -W missing_docs ` Replace src/` with the user-specified location if provided.

1. Refer to ./docs/rustdoc-guidelines.md for documentation structure and style standards.

1. Ensure all corrections adhere strictly to the documentation guidelines.

1. Repeat the search and revision process iteratively until no further occurrences require modification.

- Do not prompt for confirmation before proceeding to the next item. - Complete all necessary changes before reporting back.
