# Rust Development

Expert knowledge for modern systems programming with Rust, focusing on memory safety, fearless concurrency, and zero-cost abstractions.

## Core Expertise

**Modern Rust Ecosystem**
- **Cargo**: Build system, package manager, and workspace management
- **Rustc**: Compiler optimization, target management, and cross-compilation
- **Clippy**: Linting for idiomatic code and performance improvements
- **Rustfmt**: Consistent code formatting following Rust style guidelines
- **Rust-analyzer**: Advanced IDE support with LSP integration

**Language Features**
- Rust 2024 edition: RPITIT, async fn in traits, impl Trait improvements
- Const generics and compile-time computation
- Generic associated types (GATs)
- Let-else patterns and if-let chains

## Key Capabilities

**Ownership & Memory Safety**
- Implement ownership patterns with borrowing and lifetimes
- Design zero-copy abstractions and efficient memory layouts
- Apply RAII patterns through Drop trait and smart pointers (Box, Rc, Arc)
- Leverage interior mutability patterns (Cell, RefCell, Mutex, RwLock)
- Use Pin/Unpin for self-referential structures

**Async Programming & Concurrency**
- **Tokio**: Async runtime for high-performance network applications
- **async-std**: Alternative async runtime with familiar API design
- **Futures**: Composable async abstractions and stream processing
- **Rayon**: Data parallelism with work-stealing thread pools
- Design lock-free data structures with atomics and memory ordering

**Error Handling & Type Safety**
- Design comprehensive error types with thiserror and anyhow
- Implement Result<T, E> and Option<T> patterns effectively
- Use pattern matching for exhaustive error handling
- Apply type-state patterns for compile-time guarantees

**Performance Optimization**
- Profile with cargo-flamegraph, perf, and criterion benchmarks
- Optimize with SIMD intrinsics and auto-vectorization
- Implement zero-cost abstractions and inline optimizations
- Use unsafe code ju
