How does it handle complex nested conditionals?

It detects deeply nested if-let expressions and suggests refactoring them into flat 'let chains' using the && operator, significantly improving readability.

Which Rust versions does this migration skill support?

This skill targets features stabilized between Rust 1.75 and 1.88, specifically focusing on the requirements for the Rust 2024 edition.

What are the benefits of using gen blocks over manual iterators?

Gen blocks allow you to write iterator logic using familiar yield syntax rather than implementing the Iterator trait manually with state-machine boilerplate.

Does it update my project configuration automatically?

It provides the exact TOML snippets needed to update your Cargo.toml edition and rust-version fields to support 2024 features.

Can this skill help me remove the async-trait dependency?

Yes, it identifies where native 'async fn' in traits can replace the async-trait macro, though it will advise keeping it if you require dynamic dispatch (dyn Trait).

Developer Tools

Refactors Rust code to use the latest 2024 edition features like let chains, async closures, and native async traits.

About

This Claude Code skill empowers developers to seamlessly transition their projects to the Rust 2024 edition by identifying and refactoring legacy patterns into modern, idiomatic code. It proactively suggests syntax improvements such as flattening nested control flow with let chains, replacing the async-trait crate with native implementations, and utilizing generator blocks for cleaner iterator logic. By automating the detection of outdated Cargo.toml configurations and complex closure patterns, it ensures your codebase remains readable and takes full advantage of the latest compiler optimizations and language stabilization features.
