Behavior by the container status

You don't have to start the container via serverless rust:start before running this command. But the behavior changes if the container is running or not.

If the container is running

This command invokes the lambda function immediately and let the container running after the invocation.

If the container is not running

This command starts the container before the invocation according to the configuration in serverless.yml.(See rust:start.) And after the invocation this command stops and removes the container.
