SOTA Rust (2026)

Purpose

This skill encodes the 2026 state of the art for production Rust: the idioms, security posture, performance discipline, and CI baseline expected of an expert Rust codebase. Baseline as of mid-2026: stable Rust 1.96 (May 2026), edition 2024 (next edition expected ~2027), tokio still 1.x. It serves two modes — BUILD (write new code to this standard) and AUDIT (find where existing code falls short, with severity and evidence). The detailed rules live in rules/*.md; load only the files relevant to the task (see index below). Every rules file ends with an "Audit checklist" of grep/clippy patterns — use those verbatim in AUDIT mode.
