Type Safety

Rust Is Breaking Its Own Rules. That’s Exactly Why It’s Winning.

Rust’s 2026 goals introduce reflection and comptime — features that seem to betray the language’s core philosophy of compile-time safety. But the real story is more nuanced: Rust isn’t abandoning its principles, it’s redefining them. By moving reflection into the compile-time world, Rust is attempting to give developers dynamic power without runtime surprises. This could make Rust viable for domains long dominated by garbage-collected languages — and redefine what a systems language can do.

I Spent 3 Years Fighting Axum’s Type System. Then I Wrote My Own IDL.

After years of fighting Axum’s complex type system and inconsistent OpenAPI generation, one developer built a tool that lets you define your API once and generate Rust, OpenAPI, and TypeScript code from a single IDL. The lesson: the best code is the code you never write.

Rust’s Type Safety Is a 50-Year-Old Idea. The Revolution Is Something Else Entirely.

Rust’s type safety is often hailed as a breakthrough, but the core concept was already implemented in the 1970s by the KSOS secure Unix operating system. The real innovation isn’t the type system itself — it’s the ecosystem, tooling, and developer community that finally made a decades-old idea practical. This history warns developers not to ignore proven solutions that simply lacked the right timing and infrastructure.
