Prerequisites Familiarity with the Rust programming language and its syntax Basic understanding of how compilers work Part 1: Setting Up Your Development Environment Installing RustOverview of Rust installation options (Rustup, package managers, manual installation) Installing Rust using Rustup Setting up the Rust development environment

Today’s plan: Pernosco! And a RRC retrospective Felix Klock will lead us through a tutorial of Pernosco Followed by a short Q&A The recording of Felix's talk will be available on his YouTube channel. Retrospective In RRC tradition we discuss what has worked, hasn't worked and what needs improvement. We'll add our thoughts to this hackmd.

Pernos.co demo This document was used to drive a demonstration of pernos.co. You can see that demo on YouTube, here: https://youtu.be/uTc7KCBbVFI?t=87 [toc] Links to pernos.co sessions {%hackmd gWG5XO-XRK6GdyVkMBqV4A %} Basics

Today's plan Idea Niko explains some interesting things (15 minutes) Experimental period (15 minutes): Come up with a working theory for how things work Come up with 2 or 3 interesting examples Sharing period (30 minutes):

Today's plan: Pernosco! Pernosco link Link at visit_item call Example program: fn f() { g(); // Since there are no local variables in scope yet, this resolves to the item. let g = || {}; // "the local variable"

Pattern for this time Broad / deep 10 minutes reading 5 minutes take notes 20 minutes of chat Note-taking While you read, take notes however you prefer. You can use this hackmd but you can also use paper or your brain.

RRC FTW Welcome to the Rustc reading club! Goals: Get familiar with the "patterns" of rustc Learn what supporting resources are available Get vague idea of what code does what Deepen understanding of specific pieces of code Have fun! :rainbow: :unicorn_face:
