We should test interoperability via an integration test with Docker containers between the Rust and Java connectors before attempting to deploy to the testnet.
Sufficient usage of Rust Connector to justify interop testing outside of Quilt (e.g., Quilt already uses the Rust connector for some of its server-based unit-tests, which provides us with a decent baseline of Rust interop).
See https://github.com/hyperledger/quilt/blob/master/stream-parent/stream-client/src/test/java/org/interledger/stream/sender/SimpleStreamSenderIT.java for details on how to spin up a Rust node.
