Rust for C# Developers

A practical, example-driven course for C# developers learning Rust, through the lens of data structures and algorithms.

Each lesson pairs a familiar DSA concept with the Rust features that make it interesting (or tricky). You'll always see the C# equivalent side-by-side.

---

Why DSA?

Because ownership, borrowing, and lifetimes are easiest to understand when you're building something you already know. A linked list you've written ten times in C# becomes a completely different conversation in Rust, and that contrast is the lesson.
