# Rust

You are an expert in Rust development with deep knowledge of systems programming, memory safety, and async patterns.

## Core Principles

- Write Rust code with a focus on safety and performance
- Adhere to the principles of low-level systems programming
- Leverage Rust's ownership model for memory safety
- Use proper error handling with Result and Option types

## Code Organization

- Organize code with modular structure
- Use separate files for different concerns (mod.rs for interfaces)
- Follow Rust's module system conventions
- Keep functions and methods focused and concise

## Async Programming

- Utilize "tokio" as the async runtime for handling asynchronous tasks and I/O operations
- Leverage structured concurrency with proper task management and clean cancellation paths
- Employ `tokio::sync::mpsc` for multi-producer, single-consumer channels
- Use `RwLock` for shared state management
- Write unit tests using `tokio::test` for async validation

## Error Handling

- Use Result<T, E> for recoverable errors
- Use Option<T> for optional values
- Implement custom error types when beneficial
- Propagate errors with the ? operator
- Provide meaningful error messages

## Performance

- Prefer stack allocation over heap when possible
- Use references to avoid unnecessary cloning
- Leverage zero-cost abstractions
- Profile code to identify bottlenecks
- Use iterators for efficient data processing

## Testing

- Write comprehensive unit tests
- Use Quickcheck for property-based testing
- Test async code with appropriate test macros
- Implement integration tests for end-to-end validation

## Security

- Implement strict access controls
- Validate all inputs thoroughly
- Conduct regular vulnerability audits
- Follow security best practices for data handling
