echo

Echo Example

This is a simple example that demonstrates the basic request-response pattern using the cmd-stream library. Unlike other examples that use the high-level Sender, this example shows how to use the low-level Client directly.

Features

• Direct Client Usage: Demonstrates how to create and use a ccln.Client for sending individual Commands.
• Async Results: Shows how to handle Results via Go channels using the client.Send method.

Key Components

• Message: A simple string-based Command and Result type.
• ClientCodec & ServerCodec: Simple custom codecs for the Message type.

Running the Example

From the root of the echo directory, run:

go run .

Expected Output

Starting server on 127.0.0.1:9000...
Connecting to server...
Sending message: "one two three"
Received echo... Result: "one two three"
