"Rust for Impatient Developers" (RFID) is an interactive intro to Rust that skips programming 101, history, other fluff.

Key features:

* Tells you "how to write a function in Rust". Doesn't tell you "what is a function"

* Distraction-free. Introduces exactly one simple idea at a time, no more

* Includes simple interactive questions to verify you understood correctly

* 100% free. Mobile friendly. Tracks and saves your progress.

Why we built this:

We're the makers of CodeCrafters, which offers advanced programming challenges for developers. e.g Build your own BitTorrent in Rust.

Our users repeatedly kept asking for a Rust intro resource that offered "just enough Rust knowledge to get started on a reasonably complex first Rust project".

Initially, we wanted to recommend an external resource.

* But books were too long & too intense

* Tutorials weren't interactive or saving progress

* Jumping right into a Rust project is also too daunting

So we built RFID :)

Please try it out, we'd love any feedback, it's early days. https://app.codecrafters.io/tracks/rust

Questions:

* What could we improve in our current user experience?

* What Rust related topics would you like to see covered?

* What else is difficult about learning Rust? (besides syntax/concepts)
