Thanks for this wonderful writeup!

Our embedded TCP/IP stack now has binding API to write Rust applications. picoTCP is a size, speed and feature conscious open source TCP/IP stack for embedded devices.

These Rust bindings are still very much work in progress, and we'd be glad to get any feedback or help on this!

Maxime, amazing work! I haven't looked at the code yet... But very curious how it works for demo/testing on Linux, does it use tun/tap device or something like that?

Yup, does indeed use tun or tap (your choice)!

What about using a more modern, future-proof TCP/IP stack like PicoTCP? https://github.com/tass-belgium/picotcp/

Maxime, that's what I was thinking too! But nobody know what these guys are doing, as you can see above...
