OK this is reasonable. Perhaps my experience skews towards the lower-level a bit too much. And it's also reasonable I'm misusing the language given it's not my day job.

To answer your question, I'm referring to much of the networking code in socket2 / socket, which uses MaybeUninit when doing non-standard stuff like forming your own packets. (RAW)

Yep, I definitely buy that if you're doing very low-level stuff, C or C++ might be more ergonomic than Rust. But I don't think that covers most of the real-world use of C++.

I'm not too familiar with `socket2` but normally in Rust to construct a buffer with arbitrary bytes in safe code you would first zero it out and then write it. Using `MaybeUninit` there is presumably just a micro-optimization to avoid having to memset things to zero.
