Examples: Rust Neptune client & Gremlin client

There is a Gremlin Rust client located at https://github.com/wolf4ood/gremlin-rs/. It is not one of the official Apache TInkerPop Gremlin clients but there are people using it with Neptune.

That repo includes some sample code here https://github.com/wolf4ood/gremlin-rs/tree/master/gremlin-tutorial/src/chapters

Keep in mind though, that Amazon Neptune, to a Gremlin client, looks just the same as a Gremlin Server. The difference being instead of connecting to (for example) "localhost" running on your desktop/laptop, you connect to the remote Neptune endpoint.

There are some considerations to take into account there in terms of how you allow access to the Neptune VPC, but those are the same with any of the clients.

Please let us know if you have additional questions.
