Neqo (Mozilla) and Quiche (Cloudflare) both implement QUIC and HTTP/3. I believe they are both developing an implementation of WebTransport.

Mozilla has a Rust QUIC implementation (one of three good ones in Rust) https://github.com/mozilla/neqo
I'm not sure why it's not used here.
Which QUIC crate should I use
3 projects | /r/rust | 28 Dec 2021

As an code hobbyist I'm working on an opensource project where I would be happy to use QUIC. I did a little research and found Quinn and Quiche but also the Mozilla's implementation for which I couldn't find crate Neqo.

Is it possible to compile quicly cli (referenced in the blog post) with musl instead of glibc. I had to add signal.h and it then compiled successfully but I got illegal instruction segfault when executing cli.

There are a few Rust alternatives for QUIC. Anyone tried them and have comments.

The reason is the need to have total flexibility (control). [0]
I reckon to make it as painless as possible to integrate it into Firefox. Also probably a tiny bit of not-invented-here syndrome too :)

Ask HN: GitHub Download Hash Change?
2 projects | news.ycombinator.com | 1 Feb 2022
Today, an issue was raised in one project I use, because their build system rejected an invalid sha256sum while downloading a dependency from a GitHub zip file.
The offending dependency is usrsctp (https://github.com/sctplab/usrsctp) at commit 9d6b99b:
https://github.com/sctplab/usrsctp/archive/9d6b99b10a70f7a63d21cd80d03c353da9ac19d3.zip

I am sure there are even more implementations that I am not aware of.

People don't make these decisions for technical reasons only. Career wise it is a bad choice to spend your time working on pre-existing technologies. You don't become a distinguished engineer by iterating on existing technologies. You become one by being the creator of something new.
I think QUIC is great and does a good job solving the problems it was designed to solve. It is disingenuous to pretend these decisions were made only for technical reasons.
