我试着做this piece of Ruby个:
def color=(color)
@color = color
any_bar = UDPSocket.new
any_bar.connect HOSTNAME, @port
any_bar.send @color, 0
any_bar.close
end
如果没有bind()，我想不出其他办法来达到initialize a UdpSocket from the Rust API documentation.
我会try ::bind("0.0.0.0:0")-这应该让O/S为您 Select 一个IP/端口.这可能足以让一个临时套接字发送一个简单的数据报.
Note: this is what happens too when using sendto() on an unbound UDP socket too, e.g. using the fd returned from the socket() system call without calling bind() - the O/S allocates an IP/port to send your datagram from.
