Repository: rust-embedded/awesome-embedded-rust (language: rust)

Issue:
Drone-os
I came a cross this library yesterday, thought I might put it here as I didn't see it here:
https://github.com/drone-os 
I'm not very good with embedded so I am not sure which projects should be listed in here.


Discussion / hints:
@elpiel Sounds great. Mind creating a PR to add it?
Which section should it be added to?

PS: You can assign me to the issue.
@elpiel [Tock](https://www.tockos.org/) is added in https://github.com/xoac/awesome-embedded-rust/tree/master#books-blogs-and-training-materials But I think there could be new section with rust RTOSes?
