Thought my work belongs here.
I wrote an Unikernel that can support a web server in Rust from scratch. Essentially I have used the mini OS written by Philip Opperman and wrote an Ethernet driver on top of it in Rust with no_std. Also I have achieved Transmitting and Receiving UDP packets on that server.
Incase someone is interested to look it up. (package structure was inspired from QuiltOS.)
