Module visitor 

Rust source file visitor for LOC counting.

This module provides the core parsing logic for analyzing Rust source files and categorizing lines as code, comments, documentation, or blanks.

Acknowledgment

The parsing logic in this module is adapted from cargo-warloc by Maxim Gritsenko. Many thanks to the original author for the excellent implementation. cargo-warloc is licensed under MIT.

Modifications from original

• Adapted to use rustloclib’s LocStats and Locs types
• Added from_reader constructor for testing without files
• Changed from whitespaces to blanks field naming
• Added proper error handling instead of panics
