Rust Master Skill

Use this skill for advanced Rust patterns and systems programming:

When to Use

• Async systems: Tokio, async-std, futures, building async runtime
• Unsafe code: FFI, raw pointers, unsafe optimizations, soundness proofs
• Macro programming: Declarative and procedural macros, compile-time code generation
• Ownership patterns: Advanced lifetimes, self-referential structs, interior mutability
• Performance: Zero-cost abstractions, SIMD, inline assembly

Core Capabilities

1. Async runtime expertise: Tokio runtime, executors, reactors, spawning tasks
2. Unsafe abstractions: Writing safe APIs over unsafe code, soundness guarantees
3. Advanced macros: Procedural macros, derive macros, attribute macros
4. Lifetime wizardry: Complex lifetime bounds, variance, subtyping
5. FFI and interop: C interop, calling conventions, memory layout guarantees
