Teaching Rust to Python developers

[tomshlomo]

Recently, at my workplace (Via), a colleague and I taught the Comprehensive Rust course to a group of about 15 Python developers.

The experience was fantastic—both we and the students learned a great deal and had a lot of fun. A big thank you for creating such an amazing resource!

We made a few modifications, primarily replacing some of the exercises and adding a section on using PyO3. We've published everything here.

We hope our additions are useful to others exploring Rust and would appreciate any feedback!

That non-empty vec, in particular, is a neat idea. Where did you insert these exercises into the course?

[tomshlomo]

@randomPoison we actually also replaced the protobuf exercise with this one (which is based on this one from LifetimeKata).

The motivation for this change is that, on our team, tasks like parsing and strings/bytes manipulation are relatively uncommon.

Additionally, I think seeing a concrete example where using a single lifetime specifier instead of two results in a compilation error is really helpful for understanding lifetime annotations. The exercise demonstrates this by allowing most tests to pass with a single lifetime specifier, while one test can only pass with two lifetime specifiers.

Oh that's great. As much as I like the protobuf exercise, it is pretty complicated and I think students spend a lot of time just wrapping their heads around what they need to do. This seems way more concise and understandable, and better demonstrates the usage of lifetimes.

I think both of these are nice improvements over our current ones, so I think these would be great to integrate :)

@randomPoison @mgeisler I’d be happy to contribute! What’s the best way to proceed? Should I just open a PR to replace the exercise(s)? That feels a bit too drastic :)

[mgeisler]

Hi @tomshlomo, actually, a PR would be great! I'm sorry that I never replied on this, but @djmitche just reminded me of this thread.

[djmitche]

I'm happy to help with the PR, too, but your authorship will ensure attribution and licensing and all of that are OK.

Thanks for sharing this! It's super nice to hear that the course is useful around the world!
