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 (using openssl-1.1k) but I got illegal instruction core dumped when executing cli.

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

Microsoft has an excellent implementation, too: https://github.com/microsoft/msquic
