Getting Started with Rust

Rust is a systems programming language focused on safety and performance 🦀. In this first post of the series we set up a toolchain^[1] and write our very first program.

Installing the toolchain

Install rustup, then confirm the compiler is available:

rustup default stable
rustc --version

Don't mix a distro-packaged rustc with rustup; conflicting toolchains cause confusing version errors.

Hello, world

Every journey starts somewhere:

fn main() {
    println!("Hello, world!");
}

Prefer cargo run over calling rustc directly — Cargo builds and runs in one step.

In the next installment we dig into traits.
