Rust Study Group

You will Never Rust Alone 🦀🦀🦀

Join Discord: https://discord.gg/wVDEm7jzJe Events on Meetup.com: https://www.meetup.com/web3devs-community/

Repository https://github.com/web3devscommunity/you-will-never-rust-alone

tldr;

• It’s 80% study, 20% social
• it’s like an Agile standup, progress update + time for self-study, then exchange for knowledge.
• it’s regular, hybrid lightweight Saturday morning session.
  • Momentum is what in need as learning Rust is a long journey

Venue

• Always Hybrid
  • Online always welcome - Want everyone to keep up wherever you are
• If you’re in SG, debuggingfuture is most likely working from here IRL (Pls confirm on discord)
  • MetaCamp
    • Shout out to them Sponsoring the venue
  • fallback locations
    • JustCo @ CrossStreet Exchange Singapore, please get hourly pass via Switch App

Agenda

• 1030 Check-in
• 1045 Work 🚀🚀🚀
• 1245-1300 Regroup & Sharings

Ideas to work on

• read a chapter of book / a video, write a summary & share to the community on discord / twitter
• many resources in the channel
• try out a sdk / library and do a demo
• BYOP bring your own project in rust
• we plan to build web3dev.community website with tickets feature, open source using YEW

Resources

• for beginner (never read abt borrow/ownership)
  • https://github.com/rust-lang/rustlings
  • https://exercism.org/tracks/rust
• Resources for intermediate (know the basics, need more practices)
  • 10 videos to watch

Check-in

• write on discord with below template
• Motivation & Keep it up is the most important goal

Template (with example)

**What I'm going to do**
- minsweeper
- rustup exercises/move_semantics

**What areas I might need help**
- studying examples for "Move", "Borrow" concept 

**Anything I plan to share**
- Pattern matching in rust (5min)

**Resources**
- https://users.rust-lang.org/t/rust-mutability-moving-and-borrowing-the-straight-dope/22166
- Programming Rust Ch.6

if you have any Questions

Post on #rust discord channel, the group and the mentors will try to get back to you!

Regroup & Sharings

• what I learnt
• other sharings
• mentor feedback

Template (with example)

**What I did/learnt**
- mechanisms of Macro
- rustlings macros/, Programming Rust Ch 21

**Anything to share**
- 1) On Rust Macro
- Comparing vs decorator https://users.rust-lang.org/t/are-derive-macros-in-rust-similar-to-decorators-in-python/46686
- Anchor's usage https://github.com/coral-xyz/anchor/blob/master/lang/derive/accounts/src/lib.rs
- Macro is really powerful. There are a lot of usage in Solana Anchor framework, 
which helped to make complicated code really clean and easy to understand.
- It's in the category of metaprogramming, while very integrated with the language
(many languages got some, while groovy is a nice example)
- "Macro template are simialr to template language in web, just output rust code" -- p.603 Programming Rust
- I read parts of the book before, but I realize without practice or active project it's a bit hard to remmeber 
or sink in, esp since most of us dont use rust at production. (Thus momentum is really key)
- Basic examples: https://doc.rust-lang.org/rust-by-example/macros.html
- Deep Dive: https://www.edx.org/course/compilers
- 2) on functional programming vs typescript

**Any Help you need**
- Inspire me with fun macro use cases~~~

We want everyone to practice explaining their code, which is not only abt presentation skills, but think more thoroughly (google "rubber duck debugging")

• What I learnt (100 words+ / 3min+ presentations in call or loom)
• show & Tell - Code Examples
• always try to post to the #rust channel too
• Questions (write on discord )
• In case anyone have to go early, you can also use loom

Community-driven: How to Organize / Logistics the meetup

Try to document such that we could self-organize

• Steps
  • Venue check
  • Create a discord thread on #rust channel for checkin
  • tweet & noitfy if we got a place IRL
  • host the checkin / sharing calls
  • Call for mentors
  • Consolidate any looms or resources
• Prefer Discord first → documentation for better engagement
  • will move to more real-time open source collaborative platform soon
    • try to do github
