Custom Errors Are Non-Negotiable in My Rust Applications

Custom Errors Are Non-Negotiable in My Rust Applications Custom Errors Are Non-Negotiable in My Rust Applications Centralizing error management using a custom AppError enum, combined with map_err and From traits, solves the type chaos of Rust services, establishing a clean, single-source contract across the whole codebase, WITHOUT the need for janky 3rd party crates. Nightmare to Cohesive Design When you first start dipping toes into Rust - especially when a service interacts with diverse...

Dependency-Guided Repository-Level C-to-Rust Translation with Reinforcement Alignment

arXiv:2604.02852v2 Announce Type: replace Abstract: Automating C-to-Rust migration is critical for improving software security without sacrificing performance. Traditional rule-based methods struggle with diverse C idioms, often producing rigid and unidiomatic Rust code. Large Language Models (LLMs), trained on massive code corpora, offer a promising alternative by leveraging cross-language generalization to generate more idiomatic and maintainable Rust code.

Introduction – Rust for Python Programmers

Rust for Python Programmers: Complete Training Guide A comprehensive guide to learning Rust for developers with Python experience. This guide covers everything from basic syntax to advanced patterns, focusing on the conceptual shifts required when moving from a dynamically-typed, garbage-collected language to a statically-typed systems language with compile-time memory safety. How to Use This Book Self-study format: Work through Part I (ch 1–6) first — these map closely to Python concepts...

Bun Has Been Converted to Rust. Now What?

On May 14, PR #30412 merged into Bun's main branch: a little over a million lines of Rust, 6,755 commits, generated almost entirely by Claude Code agents over nine days. Anthropic, which acquired Bun in December, supplied the agents. The Zig implementation that powered Bun is gone.

Why the Arctic's rivers are rusting now and where toxic orange water could spread next

Why the Arctic's rivers are rusting now and where toxic orange water could spread next Sadie Harley Scientific Editor Robert Egan Associate Editor Scientists have identified the two biggest reasons that once-pristine rivers across the Arctic are growing cloudy with toxic orange iron particles that smother insects and suffocate fish. A new study published in Communications Earth & Environment builds on earlier research documenting widespread contamination in Alaska's Brooks Range. As the...

Pure Borrow: Linear Haskell Meets Rust-Style Borrowing

arXiv:2604.15290v4 Announce Type: replace Abstract: A promising approach to unifying functional and imperative programming paradigms is to localize mutation using linear or affine types. Haskell, a purely functional language, was recently extended with linear types by Bernardy et al., in the name of Linear Haskell. However, it remained unknown whether such a pure language could safely support non-local borrowing in the style of Rust, where each borrower can be freely split and dropped...

RISE: A Rust Library for Inverted Index Search Engines

arXiv:2606.07187v1 Announce Type: new Abstract: Inverted indexes are a crucial data structure for efficient information retrieval in large text corpora. They enable fast full-text search by mapping each term to the documents in which it appears, on top of which efficient algorithms quickly retrieve the documents relevant to a user query. We present RISE, a novel inverted index library implemented in Rust, designed to deliver high performance and efficiency for information retrieval tasks.
