How does this improve developer productivity?

By favoring methods over standalone functions, it enhances IDE autocomplete and makes the relationship between data and operations more explicit and discoverable.

What is the benefit of using newtypes for domain concepts?

Using newtypes (like struct Inches(f64)) allows the Rust compiler to catch logic errors, such as accidentally passing pixels into a function expecting inches.

Does this skill work for non-porting tasks?

Yes, while designed for the pikru C port, the principles apply to any Rust project where you want to ensure the code is idiomatic and follows best practices.

What is the primary purpose of the idiomatic-rust skill?

It provides guidance on porting C code to Rust using idiomatic patterns, such as using the type system for safety instead of performing a direct, line-by-line translation.

How does it handle C-style function arguments?

The skill suggests replacing 'boolean flag soup' with Enums and moving logic into methods on the specific types that hold the relevant data.

Transforms C codebases into idiomatic, type-safe Rust patterns by prioritizing behavior over literal translation.

概要

The Idiomatic Rust skill is designed to assist developers in porting legacy C code to Rust without falling into the trap of 'writing C in Rust.' It provides architectural guidance on moving logic into struct methods, using the newtype pattern to prevent unit errors, and replacing ambiguous boolean flags with expressive enums. By treating the original C source as a behavioral specification rather than a template, this skill ensures that ported projects like pikru remain maintainable, safe, and true to Rust's unique design philosophy.
