There is the websocket service stored in the url variable.

• To connect to the service asynchronusly we are using (connect_async) method.

Connecting to the server .

• There will be lot of errors regarding the async functions used,
  • First mark the main function under tokio #[tokio::main] by doing like this above the main function.
  • connect_async is method under tokio-tungstenite, so import from that.

Sending and recieving messages

• To send and recieve messages from the service agent, we need to split up the websocket stream into a write and read stream.

• .split() method is used for spliting the stream into multiple stream. Let's take two varaibles known (write)[For writing] and (read)[for reading]

• For writing messages to the stream

  • (write) write.send(msg); is used, this is method used from futures_util::sink::SinkExt crate in rust.
  • let msg = Message::Text() is used for declaring the message
  • At last its an async function so do add write.send(msg).await at the end.

• For reading messages to the stream

• You can first check if there is any message by putting it in a if stattement, --> read.next() to pull out the messages

• If there is any than print the messages.

Your Websocket is ready !! 🥳🥳🥳
