Channels

#description

In Rust, channels are the preferred way to communicate between threads. Channels are essentially message-passing interfaces that allow threads to pass data back and forth. Here, one thread will send a message or data to another thread through the channel, the receiving thread will process that data and then respond back through the channel.

Channels are useful when multiple threads that are running concurrently in a program need to communicate with each other. Using channels ensures that data share between threads is synchronized correctly, leading to fewer bugs and faster performance.

Channels in Rust are created using the std::sync::mpsc module.

There are two types of channels provided by the module:
  1. Sender: A sender is used to send data or messages through the channel to the receiving thread.
  1. Receiver: A receiver is used to receive data or messages from the channel sent by the sender.

With the above constructs, Rust's mpsc module provides a nice abstraction over cross-thread communication, thereby making it easier for developers to write multi-threaded programs that are correct and efficient.
