The volatile crate provides a safe wrapper type for implementing volatile read and write operations. This is useful for accessing memory regions that have side-effects, such as memory-mapped hardware registers.

We merged the following PR this month:

Other Projects

In this section, we describe updates to Rust OS projects that are not directly related to the rust-osdev organization. Feel free to create a pull request with the updates of your OS project for the next post.


(Section written by @nicholasbishop)

I've released a new Rust crate for reading ext4 filesystems. It's easy to use, with an API very similar to std::fs. The crate is no-std compatible, but does require an allocator.

Note that by design this crate will remain read-only; writing to an ext4 filesystem is not a goal.

Thanks to @tedbrandston for doing a ton of code review on this project!
