Function rustix::net::recvfrom_uninit

pub fn recvfrom_uninit<Fd: AsFd>(
    fd: Fd,
    buf: &mut [MaybeUninit<u8>],
    flags: RecvFlags
) -> Result<(&mut [u8], &mut [MaybeUninit<u8>], Option<SocketAddrAny>)>

recvfrom(fd, buf, flags, addr, len)—Reads data from a socket and returns the sender address.

This is equivalent to recvfrom, except that it can read into uninitialized memory. It returns the slice that was initialized by this function and the slice that remains uninitialized.
