What this room is for

Ferrugo is a public room that teaches Rust. A visitor can read where the language came from, how it sits beside Python, JavaScript, and Java, and why engineers reach for it. The first page is a short path: the shape of a tiny program, the syntax that writes it, and ownership, borrowing, and Result. /further continues on its own page with traits, generics, lifetimes, modules, iterators, closures, threads, and async.

Checks are graded in the browser. A program is compiled only when the visitor chooses Try it, and then on the official Rust playground. This site does not run a compiler and does not keep an account.

The name of the product is Ferrugo.
