Purpose

This skill provides expertise in advanced Rust programming, focusing on core language features and ecosystem tools to build efficient, safe systems code.

When to Use

• When implementing memory-safe code with ownership, borrowing, or lifetimes to prevent common errors like data races.
• For projects requiring asynchronous programming with Tokio, error handling via anyhow/thiserror, or managing multi-crate setups with Cargo workspaces.
• In scenarios involving unsafe code for performance-critical sections, or defining custom behaviors with traits.

Key Capabilities

• Manage Rust's ownership model: Use references (&T) and lifetimes ('a) to borrow data without transferring ownership.
• Implement traits: Define and use trait objects for polymorphism, e.g., trait Debug { fn fmt(&self); }.
• Handle async with Tokio: Run asynchronous tasks using tokio::main and futures.
• Error management: Leverage anyhow for simple error wrapping and thiserror for custom error types.
• Cargo workspaces: Organize multi-package projects with Cargo.toml workspaces for dependency sharing.
• Unsafe operations: Use unsafe blocks for raw pointers or FFI, ensuring safety invariants are maintained.
