In plain English

This repository is a structured course for learning the Rust programming language from scratch through 100 hands-on exercises. Rust is a systems programming language known for being fast and for catching many categories of software bugs before the program even runs, but it has a reputation for a steep learning curve. This course is designed to reduce that friction by breaking the learning process into small, incremental steps. The course is aimed at people who have heard of Rust but have not yet written any of it. You do not need prior experience with Rust specifically, though the course assumes some general programming background. By the end, the goal is that you can start writing your own Rust programs. To get started, you visit rust-exercises.com and follow the setup instructions there. You need Rust installed on your machine, which you get via a tool called rustup. An IDE with Rust autocompletion is optional but recommended, the README suggests RustRover or Visual Studio Code with a specific extension. Solutions to all 100 exercises are available in a separate branch of the same repository, so you can check your work or get unstuck without leaving GitHub. The course was written by Mainmatter, a software consulting firm that offers Rust training and consulting as a commercial service. The course content itself is released under a Creative Commons license that allows non-commercial use with attribution.

Copy-paste prompts

Prompt 1

I'm working through the mainmatter 100-exercises-to-learn-rust course and stuck on a borrow checker error. Here's my code, explain what the borrow checker wants and how to fix it.

Prompt 2

I want to start the 100 Rust exercises. Walk me through installing rustup, cloning the repo, and running the first exercise so I see the test output.

Prompt 3

I finished a Rust exercise but my solution differs from the one in the solutions branch. Which approach is more idiomatic Rust and why?

Prompt 4

I'm halfway through the 100 Rust exercises. What key concepts, ownership, lifetimes, traits, should I make sure I've truly understood before moving to the harder exercises?
