### AI overview

SpeC2Rust translates C repositories through three stages: it structures repository intent into module specifications, generates Rust modules using those specifications and a live symbol registry to keep cross-file interfaces consistent, then batches repairs using relevant diagnostics, specification context, and source evidence. Across eight projects, its generated Rust compiled and passed the original end-to-end tests, with no raw-pointer declarations or dereferences and no unsafe lines. On projects shared with an LLM-based baseline, it reduced cost by 66.1% and input-token use by 84.7%.

### Source excerpt

arXiv:2610.34141v1 Announce Type: new Abstract: Legacy C codebases remain central to system software and performance-critical infrastructure, but their weak memory safety imposes security and maintenance risks. Recent C-to-Rust translation systems, including LLM-based translators, make automated migration increasingly feasible, yet they still struggle to recover repository-level intent, avoid raw pointers and unsafe constructs, maintain cross-file interfaces, and repair compilation and validation failures efficiently. We propose SpeC2Rust, a specification-driven pipeline for repository-level C-to-Rust translation. It has three stages: (1) Project-Intent Structuring, which decomposes a C repository into semantically coherent modules and generates persistent repository- and module-level specifications; (2) Spec-Guided Generation, which translates each Rust module against these specifications with a live symbol registry to preserve cross-file consistency; and (3) Layered-Feedback Repair, which batches repairs and injects only failure-relevant diagnostics, specification context, and source evidence for efficient compilation and test-driven correction. We evaluate SpeC2Rust on eight repository-level C projects. It generates Rust projects that compile and pass the original end-to-end tests, with no raw-pointer declarations, raw-pointer dereferences, or unsafe lines. On projects shared with an LLM-based baseline, SpeC2Rust reduces cost by 66.1% and input-token usage by 84.7%.

### AI overview

Rust's ownership model is a key adjustment when moving from C or C++: each value has one owner, memory is cleaned up when that owner leaves scope, and borrowing permits temporary access through references. The compiler's borrow checker rejects invalid uses such as accessing a value after it is no longer valid, helping prevent use-after-free and double-free bugs. The excerpt also highlights Rust's static typing, enums, pattern matching, and generics as tools for catching errors at compile time and expressing data clearly. It does not provide the full guide or develop the later steps.

### Source excerpt

Introduction: As you embark on the journey from C or C++ to Rust, you'll discover a world of exciting possibilities. Rust's emphasis on safety, concurrency, and performance can significantly enhance your programming toolkit. This beginner's guide on transitioning from C and C++ to Rust will provide a structured approach to making that transition, addressing essential concepts and practical applications. Let's dive in! Step 1: Understanding Rust's Ownership Model Concept Overview: Rust's ownership model is its most distinctive feature. Unlike C and C++, where you have pointers and manual memory management, Rust uses a system of ownership with rules that the compiler checks at compile time.
