An interesting thing is happening in Python land the last few years.

Many developers are running Rust 🦀 every day.

You might not realize it, but:

- You run Ruff / uv / ty -> Rust

- You use Polars or Pydantic -> Rust

- You swap out pre-commit by Prek and/or use just -> Rust

New exercise track 🎉

#unix classics: wc, head, grep, cut, sort, sed ...
up to a top_words capstone:
`tr -s ' ' '\n' < file | sort | uniq -c | sort -rn | head`

Taught from #Python. 🐍
You rebuild them in #Rust. 🦀

[Pybites @pybites]

Learn Rust concepts in a more fun way, going from concepts you already know. 💡

I just completed "Re-exports and API Design" on @pybites #Rust Platform 🦀🎉 https://t.co/Us9Nwd3K7V

[Bob Belderbos @bbelderbos]

I really like #Rust's Result type 🦀

[Bob Belderbos @bbelderbos]

I just completed "Visibility Rules" on @pybites #Rust Platform 🦀🎉 https://t.co/Nm5DziBpOK

[Bob Belderbos @bbelderbos]

We all love Unix tools, right? They're quite easy to emulate in Python, but how would you build them in #Rust? 🦀

Enter the new Unix tools track: 10 bites reimplementing wc, grep, cut, sort, uniq and friends.

Give them a go and practice writing idiomatic Rust with iterators. 🚀

[Bob Belderbos @bbelderbos]

I earned the Orange Ninja Belt on @pybites Rust Platform 🦀🥷 - sharpen your #Rust skills too 💪 https://t.co/62KgoYCVAP

[Bob Belderbos @bbelderbos]

I just completed "cut: Extract a Field" on @pybites #Rust Platform 🦀🎉 https://t.co/aYruqLscVo

filter_map() 😍

[Bob Belderbos @bbelderbos]

#Rust tip: a 'match guard' can be added to filter the arm.

Nice feedback from somebody going through our #rust exercises:

> I started with the Rust Platform - exercises and really enjoy the comparison made with Python at each one of them! It allows to appreciate both languages in one go. Plus I love the reference made in some of them to docs (Rust Programming Language)!

But also code the Bites, you'll be forced to figure things out yourself (increasingly important now with agents writing most code!), and then look for more idiomatic ways to do things 📈

Start with the 15 intro ones: https://t.co/TusE5JfaY0

[Bob Belderbos @bbelderbos]

Need to learn more of Rust's built-in helpers :) - me writing `parse_with_optional_sign` helper for a Bite that peeked at the first char, stripped a leading `+`/`-`, parsed the rest, and re-applied the sign. Of course that's well covered by the std lib!

[Bob Belderbos @bbelderbos]

Nice I could 'forget' my #rust bites after months of creating them, and have some nice *deliberate practice* today 🦀🎉

Interested in jumping into Rust? Join me here and let me know how these exercises go for you?

[Bob Belderbos @bbelderbos]

Some more good #rust learning today, wrapping up the intro Bites 🦀

Especially tokenizer + parser (10 and 15) will throw a curve ball here and there, and they form a nice (simplified) sneak preview of things we have you build in our JSON parser cohort. 💪

[Pybites @pybites]

@bbelderbos try it yourself: https://t.co/vNEDT5rwrA

[Bob Belderbos @bbelderbos]

I really like that match/case is exhaustive in #Rust 🦀

It's a good example where the compiler helps you by forcing you to handle all cases.

[Pybites @pybites]

@bbelderbos Deliberate practice for the win, now even more important with LLMs producing more code!
