Programming with TCP and UDP in Rust

As discussed earlier, TCP and UDP are the fundamental transport layer network protocols for the internet. In this section, let's first write a UDP server and client. Then we'll look at doing the same using TCP.

Create a new project called tcpudp where we will write the TCP and UDP servers and clients:

cargo new tcpudp && cd tcpudp

Let's first look at network communication using UDP.

Writing a UDP server and client

In this section, we'll learn how to configure UDP sockets, and how to send and receive data. We'll write both a UDP server and a UDP client.

Starting with the UDP server

In the example shown, we're creating a UDP server by binding to a local socket using UdpSocket::bind. We're then creating a fixed-size buffer, and listening for incoming data streams in a loop. If data is received, we are spawning a new thread to process the data by echoing it back to the sender. As we already...
