Function rustix::net::recv_uninit

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

recv(fd, buf, flags)—Reads data from a socket.

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