Rust Development

# Rust Project

This is a Rust project using Cargo.

## Project Structure
- `src/main.rs` - Binary entry point
- `src/lib.rs` - Library root
- `src/bin/` - Additional binaries
- `tests/` - Integration tests
- `benches/` - Benchmarks

## Code Style
- Follow Rust API guidelines
- Use rustfmt for formatting
- Use clippy for linting
- Prefer &str over String for function parameters

## Error Handling
- Use Result<T, E> for recoverable errors
- Use thiserror for library error types
- Use anyhow for application error handling
- Avoid unwrap() in production code

## Ownership & Borrowing
- Prefer borrowing over cloning
- Use Cow<str> when ownership is conditional
- Minimize lifetime annotations where possible
- Use Arc/Mutex only when truly needed

## Commands
- `cargo run` - Run the application
- `cargo test` - Run all tests
- `cargo build --release` - Build optimized binary
- `cargo clippy` - Run linter
- `cargo fmt` - Format code
- `cargo doc --open` - Generate and open docs
