I wrote an API Client in Rust recently for EVE-NG, a network emulator. Some of its API endpoints (that represent lists of things) return different JSON representations for the same endpoint depending on the state of the instance.

When the lab has no nodes, the data is an empty array: { "data": [], } When the lab has nodes, the representation changes from an empty...
