Installing Rust: `rustup` is Your New Best Friend - Day 02

Setting up a Java project used to mean downloading a JDK, setting JAVA_HOME, maybe fighting with your IDE, and picking a build tool. Rust makes this refreshingly simple.

One command to rule them all #

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

That’s it. This installs rustup — Rust’s toolchain manager. Think of it as the equivalent of SDKMAN for Java, except it’s the official way to install Rust and everyone uses it.

What gets installed #

After running the above, you get three tools:

  • rustc — the Rust compiler (you’ll rarely use this directly)
  • cargo — the build tool, package manager, test runner (you’ll use this constantly)
  • rustup — manages Rust versions and components

Verify it worked #

rustc --version
cargo --version

You should see something like rustc 1.78.0 and cargo 1.78.0.

Updating Rust #

This is where rustup shines. Upgrading is one command:

rustup update

No downloading a new JDK zip. No updating JAVA_HOME. No drama.

IDE support #

Install the rust-analyzer extension in VS Code or IntelliJ IDEA (via the Rust plugin). It gives you autocomplete, inline errors, and type hints — everything you’re used to in Java.
