[Talk::Overflow #18] EuroRust 2025 is out.

I just released the latest issue of Talk::Overflow, diving into the technical heart of EuroRust 2025 in Paris. The biggest takeaway? The conversation has shifted. We aren't talking about "why" Rust anymore—we’re talking about how to scale it to millions of users and lines of code.

Here are the 3 talks from the recap that every engineer should have on their radar:

1️⃣ Rendering at 1 Million Pixels/ms Conrad Irwin (co-founder of Zed) showcased GPUI. Seeing how Rust’s ownership model allows a UI framework to outperform traditional C++ frameworks while staying declarative is a masterclass in high-performance graphics.

2️⃣ Data Engineering is shifting. Traditionally the land of Python and Java, data-intensive infra is moving to Rust. Michele Vigilante laid out a clear blueprint for building high-throughput pipelines with datafusion that drastically cut cloud costs and latency.

3️⃣ The "Human" Impact of Performance. One of the most powerful sessions was by Brooke, who built a high-performance digital forensics tool in Rust to combat human trafficking. It’s a stark reminder that memory safety and speed aren't just technical benchmarks—they have real-world consequences in high-stakes environments.

The Bottom Line: Whether it's System76 shipping a full desktop environment (COSMIC) in Rust or Meilisearch rebuilding search architecture from the ground up, the ecosystem has reached a level of maturity that is hard to ignore.

I’ve summarized all 20+ talks—from compiler internals (HIR/MIR) to deterministic simulation testing—in the full post.
