Set Up Rust

This post gives an overview of the recent updates to the Writing an OS in Rust blog and the corresponding libraries and tools. I focused my time this month on finishing the long-planned post about Async/Await. In addition to that, there were a few updates to the crates behind the scenes, including some great contributions and a new vga crate. As...

In this post, we explore cooperative multitasking and the async/await feature of Rust. We take a detailed look at how async/await works in Rust, including the design of the Future trait, the state machine transformation, and pinning. We then add basic support for async/await to our kernel by creating an asynchronous keyboard task and a basic...

This post explains how to implement heap allocators from scratch. It presents and discusses different allocator designs, including bump allocation, linked list allocation, and fixed-size block allocation. For each of the three designs, we will create a basic implementation that can be used for our kernel. This blog is openly developed on GitHub....
