Learning Rust and Lemmy

391 readers

Welcome

A collaborative space for people to work together on learning Rust, learning about the Lemmy code base, discussing whatever confusions or difficulties we're having in these endeavours, and solving problems, including, hopefully, some contributions back to the Lemmy code base.

Rules TL;DR: Be nice, constructive, and focus on learning and working together on understanding Rust and Lemmy.

Running Projects

Policies and Purposes

  1. This is a place to learn and work together.
  2. Questions and curiosity is welcome and encouraged.
  3. This isn't a technical support community. Those with technical knowledge and experienced aren't obliged to help, though such is very welcome. This is closer to a library of study groups than stackoverflow. Though, forming a repository of useful information would be a good side effect.
  4. This isn't an issue tracker for Lemmy (or Rust) or a place for suggestions. Instead, it's where the nature of an issue, what possible solutions might exist and how they could be or were implemented can be discussed, or, where the means by which a particular suggestion could be implemented is discussed.

Rules

  1. Lemmy.ml rule 2 applies strongly: "Be respectful, even when disagreeing. Everyone should feel welcome" (see Dessalines's post). This is a constructive space.
  2. Don't demean, intimidate or do anything that isn't constructive and encouraging to anyone trying to learn or understand. People should feel free to ask questions, be curious, and fill their gaps knowledge and understanding.
  3. Posts and comments should be (more or less) within scope (on which see Policies and Purposes above).
  4. See the Lemmy Code of Conduct
  5. Where applicable, rules should be interpreted in light of the Policies and Purposes.

Rust for Lemmings "Reading Club" Alternate Slot (18:00 UTC+2) - Session 13 (jlai.lu)

What?

I will be holding the thirteenth of the secondary slot/sessions for the Reading Club, also on "The Book" ("The Rust Programming Language"). We are using the Brown University online edition (that has some added quizzes & interactive elements).

Last time we started chapter 6 (enums & pattern matching). We read through 6.1 and learned how to define enum variants in tuple or struct form. We also learned about the Option<T> enum that Rust provides us with. This time we'll begin section 6.2 and learn about the match control flow construct.

Previous session details and recording can be found in the following lemmy post: https://jlai.lu/post/7532130

Why?

This slot is primarily to offer an alternative to the main reading club's streams that caters to a different set of time zone preferences and/or availability.

(also, obviously, to follow up on the previous session)

When ?

Currently, I intend to start at 18:00 UTC+2 (aka 6pm Central European Time) on Monday (2023-06-17). If you were present for a previous session, then basically the same time-of-day and day-of-week as that one was.

EDIT: here's the recording https://youtu.be/W1fjxCwtwfM

Please comment if you are interested in joining because you can't make the main sessions but would prefer a different start time (and include a time that works best for you in your comment!). Caveat: I live in central/western Europe; I can't myself cater to absolutely any preference.

How ?

The basic format is: I will be sharing my computer screen and voice through an internet live stream (hosted at https://www.twitch.tv/jayjader for now). The stream will simultaneously be recorded locally and uploaded afterwards to youtube (also, for now).

I will have on-screen:

  • the BU online version of The Book
  • a terminal session with the necessary tooling installed (notably rustup and through it cargo & "friends")
  • some form of visual aid (currently a digital whiteboard using www.excalidraw.com)
  • the live stream's chat

I will steadily progress through the book, both reading aloud the literal text and commenting occasionally on it. I will also perform any code writing and/or terminal commands as the text instructs us to.

People who either tune in to the live stream or watch/listen to the recording are encouraged to follow along with their own copy of the book.

I try to address any comments from live viewers in the twitch chat as soon as I am aware of them. If someone is having trouble understanding something, I will stop and try to help them get past it.

Who ?

You! (if you're interested). And, of course, me.

We managed to get through the rest of the entire chapter! Next session will start chapter 7 (on packages, crates, and modules).

Nice work. Chs 5 and 6 are lighter weight after ch 4, as they're more basic language features stuff, so it makes sense you made quicker progress than you thought.
