How To Compile Rust Code Faster: Compiler 101 — Benjamin Bouvier at Rust in Paris 2025 🦀 Conf

Description

*In Rust in Paris 2025* , Benjamin Bouvier, *Rust hacker at Element* , tackled one of the few pain points of Rust: its *infamous compile times* . ⏱ Why does Rust sometimes compile slowly? What does a compiler actually do? And how can we speed it up without compromising quality? Benjamin walked through the *high-level steps of a compiler* , stopping at each stage to explore ways to reduce compile times, make informed trade-offs, and leverage the right tools. He also shared a *real-world case study* of cutting down compile times in a production project. 🔍 *What you’ll learn in this talk:* * The main stages of the Rust compiler * Why Rust compilation is slow in some cases * Practical strategies and trade-offs for faster builds * Tools that help diagnose and reduce compile times * A case study of improving real-world compile times 💡 *About the speaker:* Benjamin Bouvier is a *Rust hacker at Element* , passionate about compilers, performance, and making Rust development more productive. 📅 *Rust in Paris 2026 is coming soon* — stay tuned for updates! #rustlang #rustinparis #rustprogramming #opensource #rustcommunity #compiler #performance
