Learn Rust well enough to judge it

Who it is for

Rust Primer is for people who can already program and want to become properly productive in Rust. If you come from Go, C#, Java, TypeScript, Python, C or C++, you are in the right place.

It is not a first programming course, a video series or a browser playground. You work locally, in a real editor, with the real toolchain.

How it works

Every module is a small, concrete problem: repair a function that takes ownership it does not need, replace panics with typed errors, design an API a caller can actually use. You change the code, run the compiler and the tests, and then explain the decision in your own words.

A module is finished when you have evidence:

• code that compiles
• tests that pass
• a short explanation of the central Rust decision
• a link back to the official Rust documentation
• an AI verification drill, where you challenge an answer instead of accepting it

AI is allowed. It is not trusted.

Use an AI assistant for hints, for explanations of compiler errors and for reviews of your reasoning. Do not use it as the final word. In Rust Primer, the order of authority is:

1. the code
2. the compiler
3. the tests
4. clippy and rustfmt
5. the official Rust documentation
6. human review
7. AI output, once it has been verified

Rust is unusually good for learning this way. The compiler and the test suite give definite answers, so you can check your own understanding and an assistant’s claims against something that does not bluff.
