Hey all 👋
This year I'll try to stick to Thread Thursdays, which is every Thursday I'll post a thread about #rustlang fundamentals 🦀
My goal is to help you learn 1% more Rust each Thursday, so follow me if you'd like to read them 🦋
Here are some of the best threads so far 🧵👇

No #rustlang thread today cause I’m travelling, but we’re on for next week, we should probably talk about unwrap seeing how everyone else already is 😂

🕰️ Async Basics in #rustlang
Send, Sync, Future, tokio, Pin, I'm sure you've heard a lot of intimidating terminology when it comes to async Rust, so this thread is about explaining the basics in a simple way.
We'll build a transcript generator to understand async/await, Futures
🧵👇

⛔ Error handling in #rustlang with anyhow and thiserror
Error handling in Rust can be a complex topic, especially since a lot of the patterns are different from other languages.
Let's explore some basic options and then go deeper into using anyhow and thiserror crates

Thursday Thread Preview
⛔ Error handling in #rustlang with anyhow and thiserror
👉 In this thread, I’ll break down how to handle errors cleanly and how/when to use Result vs anyhow vs thiserror
Stay tuned, coming out Thursday on 🦋 and 📤

📁 File IO in #rustlang
File system handling is a core building block of using a language effectively, and Rust makes it pretty ergonomic with the std::fs module.
Let's take a look at how to use File IO APIs in Rust with a real-world example: a grade manager for students and courses 🧵👇

We've looked at Vec and HashMap in previous threads, but what about queue usecases?
Let's build a waitlist functionality for our university database and figure out how to use VecDeque

🔒 Visibility in #rustlang
As projects grow, there's more and more code to organise and maintain. Visibility rules help you create clean APIs, prevent accidental misuse of internal code, and make refactoring safer by clearly defining public interfaces.
Let's learn more about it 🧵👇

🧇 Pattern matching in #rustlang
Pattern matching like match, if let and while let are powerful control flow constructs in Rust that allow you to compare a value against a series of patterns and execute code based on which pattern matches.
Do you know all the matching tricks?

🎓 State Machines in #rustlang
Ever wondered how to model something that changes over time like a student’s journey from an applicant to a graduate safely in Rust? How do you stop a student from graduating before they even apply?

🎡 Memory layout in #rustlang
Have you ever wondered how Rust manages memory layout and how structs you create are actually laid out? This is very important in memory constrained usecases, but also useful to know in general.
Let's take a look at some examples and optimisations 🧵👇
