📁 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 🧵👇

🔒 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 🧵👇

🏗️ Organizing Larger Projects #rustlang How do large projects like bevy or the rust compiler get broken down into manageable chunks? How do they keep the codebase modular and maintainable, and easy to work on? Do you have a single main file with 500+ LOC? Let's learn how to use workspaces🧵👇

🎭 Static Lifetime in #rustlang Lifetimes in general can be tricky for anyone learning rust, and require a lot of different attempts and practice to understand well and get right. One common lifetime is the 'static lifetime, but what does it mean? Let's figure out the details 🧵👇

🍜 Procedural macros in #rustlang Pretty sure you have all used #[derive] macros for Debug, Clone, Serialise, etc. But did you know you can write your own? Why would that be useful? While procedural macros can be a bit intimidating at first, they are super powerful. Let's make them simpler 🧵👇

🛋️ Interior mutability in #rustlang We are used to fighting the borrow checker to ensure that we don't break the ownership rules. But sometimes, we need to mutate data even when we only have an immutable reference. This is where interior mutability comes in It sounds very counter-intuitive🧵👇
