gollark: For LAN use, I mean.
gollark: I was TRYING to make UDP/IPv6 multicast work, except the libc(/POSIX? who knows) APIs for this appear to be terrible and not map onto the actual protocols at all.
gollark: I was using socket2, which provides a thin wrapper over Windows/libc sockets.
gollark: No, the libc socket APIs.
gollark: I tried to do some socket programming in Rust™ yesterday, but it failed in bizarre and incomprehensible ways. I don't think this is Rust's fault as much as the socket APIs just being really terrible and incomprehensible.
