Fundamentals with Rust

Build a CLI Distance Calculator

Harrison Kong

Do you know that according to surveys, Rust is one of the most admired computer programming languages for 8 years in a row? Rust is a language that is prized for its performance, memory safety, and concurrency, making it ideal for today’s cloud-based computing world. It is used by major technology companies such as Microsoft and Github.

In this 1-hour long project-based course, your Rust learning journey will take off with the fundamental concepts and language syntax of Rust. We will do this by building a command line interface tool that calculate distances between cities. At the end of the course, you will be able to use Rust to create and build other projects.

This course is aimed at learners who have at least intermediate level proficiency with at least one modern high level programming languages such as JavaScript, Java, C, C++, Swift, Go, Kotlin. As we will leverage that knowledge and further explore Rust’s unique features.

Reviews summary

Hands-on rust introduction for experienced developers

According to learners, this course offers a quick and effective introduction to Rust, particularly for those with intermediate proficiency in other programming languages. Students praise its project-based approach, building a practical CLI distance calculator, which helps in grasping Rust's core syntax and unique features like ownership. While many found the instructor's explanations clear and the course delivered what it promised for its short duration, some caution that the pace can be very fast. It is not recommended for absolute programming beginners, as it assumes significant prior knowledge, especially in concepts like memory management.

The course offers a quick overview rather than in-depth instruction.

"The pace is really fast, and if you're not already comfortable with programming, especially memory concepts, you might struggle."

"I found it too fast; Rust's concepts like ownership were introduced too quickly without enough detailed explanation, leaving me lost in some parts."

"It feels more like a demo than a comprehensive course; it's okay for an hour, but not a true beginner's guide to Rust."

Effectively introduces core Rust concepts like ownership.

"It really highlights Rust's unique features, especially ownership and borrowing, in a practical context. I wish it was longer."

"As a JavaScript developer, I found the examples clear and easy to follow, bridging my existing knowledge to Rust's syntax."

"Being a C++ developer, I found the parallels and differences were well-explained, which helped me pick up Rust basics quickly."

A hands-on project reinforces fundamental Rust concepts.

"The project-based approach works well for a short course; I found the CLI distance calculator engaging and it helped me grasp the basic structure of a Rust application."

"I appreciated the hands-on project which solidified my understanding of Rust fundamentals and delivered exactly what was promised."

"This was a fantastic project to get my feet wet with Rust; it's small but well-scoped for the time."

This course is best suited for experienced developers.

"It definitely needs you to know another language."

"I found this course highly recommended if you have prior coding experience, as it builds on what you already know."

"This course is not for absolute beginners; it assumes a lot of prior knowledge and isn't suitable if you're new to systems programming."
