This project has a single function called publish_time that will publish the number of seconds since it was called and repeat that count times.

All of this in the file lib.rs and there is a test in there to connect to test.mosquitto.org and publish to it. It verifies that the publishes occur by also subscribing with another connection and verifying that all the messages come through.

You can look in the Cargo.toml file to see the dependencies. Its using:

• tokio for the async executor
• pahobin/paholib use the paho mqtt library (C wrapper)
• rumqttcbin/rumqttclib use the rumqttc library (pure rust)

To build: cargo build To run tests: cargo test
