Implementing TCP in Rust

I only read the README so far but I'm not sure if the author realizes that the RFC793 being repeatedly referred to has been obsoleted by RFC9293. I encourage people needing a reference to TCP to start with RFC9293 instead. This is the updated specification that brings together changes from a number of previous RFCs.

There is also the Rust TCP/IP stack https://github.com/smoltcp-rs/smoltcp which is not mentioned as reference (and it's probably more useful to have a look there than querying ChatGPT).

ICYMI but https://datatracker.ietf.org/doc/html/rfc9293 may be a better place to start in 2023.

Oh nice. Just today I started watching Jon Gjengset's video implementing TCP in Rust https://youtu.be/bzja9fQWzdA?si=Gh4s8FHpk9vBVEwZ

This is a great initiative to help people understand how TCP works.

But an "implementing TCP in <an easy, readable language such as Python>" would be so much better IMHO. Rust is good, but not as readable pseudo-code to understand a concept.

This is something similar: https://implement-dns.wizardzines.com/

Can you please add proper error messages, because this is the main problem I have with all networking related issues: I don't get any error messages, just a dead connection.

Thanks for sharing. I look forward to going through this content.

At certain point, I tends to avoid this kind of tutorial because if you understand both topic well there is no reason why you need to learn implementing X in Y.
