We’ll start with a simple, unoptimized version and apply a series of optimizations that will take the time to solve 100,000 puzzles from over 5 minutes down to just 33 seconds, and 20,000 of the hardest puzzles from over 2 minutes down to just 17 seconds.

TL;DR New macro system: define declarative macros with the macro keyword instead of macro_rules!. Real scoping: paths inside the macro body resolve where the macro is defined, not where it’s invoked. Way better IDE UX: hover, go-to-definition, comple..."

Box<T> is not a convenience. It is a contract. It turns heap allocation — one of the most unpredictable parts of system design — into something you can trust every single time.

Yes, and Here’s the Dangerous Way People Do It Created page with "500px If you’ve spent time in Java or C#, you’ve probably seen the Singleton pattern — a way to guarantee that only one instance of a type exists in your program. It’s a design pattern that people either love (“simple global access”) or hate (“global mutable state is evil”). When I first moved to Rust, I assumed singletons weren’t even possible. After all, Rust hates global mutable state. And yet… developers still..." current

Created page with "Hook Everyone loves to chant the gospel of Rust: memory safety, fearless concurrency, no segfaults, borrow checker as your guardian angel. But here’s the truth no Rust evangelist wants on a T-shirt: Rust is only safe because of the unsafe parts. Yes. That keyword you were told to avoid like it’s black magic? That’s the engine oil.

It was a pressure test against a real workload. The surprising part was not the number. The surprising part was how little memory it required to hold that state.

Shared memory concurrency forces you into a world of mutexes, race conditions, and the constant fear that somewhere, somehow, two threads are fighting over the same piece of data. The cognitive overhead becomes overwhelming. You spend more time reasoning about locks th..." current

Released on September 18, 2025, Rust 1.90 brings one of the most impactful performance improvements in recent Rust history.

Created page with "The Rust community celebrates fearless concurrency as a revolutionary achievement. Zero-cost abstractions, ownership semantics, and compile-time guarantees that prevent data races.

You know that feeling when the terminal mocks you with 47 red lines and one smug message — “missing dependency: please reinstall”? Yeah. That.

But mastering its syntax isn’t enough. The real test comes when you have to design maintainable, scalable systems without fighting the borrow checker or drowning in lifetime annotations.
