K-std

Unikernel specifically designed to run rust applications on bare metal. It's composed of two parts:

• The std library, that is essentially a stripped down version of the official rust std.
• The K, that is the actual kernel that provides the low level funcions requiered by std.

Build

First run the following commands inside your project's folder:

$ rustup override set nightly
$ rustup component add rust-src
$ rustup component add llvm-tools-preview
$ cargo install bootimage

And finally build the image:

$ cargo bootimage

This will generate a bootable image you can run with QEMU:

$ sh run_kernel.sh

Rust nightly compiler can be unstable and crash sometimes. In rare cases you will need to regenerate the project:

$ cargo clean
