100 Exercises to Learn Rust, Updated

Summary

The post announces a major update to the free JetBrains Academy course ‘100 Exercises to Learn Rust,’ which runs inside RustRover. The course teaches Rust through hands-on exercises building a ticket management system across eight chapters from ownership to futures, assuming fluency in another language. The update adds a rebuilt introduction, an FAQ, a final challenge turning the system into an async REST API by editing Cargo.toml and verifying with a requests.http file, visible test assertions, and a dev/release profile experiment. A ‘fast track’ lets experienced users skip to the final challenge to quickly see which areas need revisiting. The post advises using AI for explanations, not code generation, and turning off AI code completion during exercises to maximize learning from getting stuck and working out solutions.

Takeaways

1. 1

   The course is free and runs inside RustRover, which is free for non-commercial use, with no setup required beyond installing the IDE and enabling the JetBrains Academy plugin.

2. 2

   The update adds a final challenge where learners turn the ticket management system into an async REST API by editing Cargo.toml and using a requests.http file to verify behavior, with all implementation decisions left to the learner.

3. 3

   The post recommends turning off AI code completion during exercises to ensure learners get stuck and work out solutions themselves, and using AI only for explanations of compiler errors.
