gRPC API Reference

Generated from Tempo's .proto files on every documentation build, so it always matches the services the server exposes.

Names are shown as the generated clients expose them - tempo_world.spawn_actor rather than WorldControlService.SpawnActor. The same name is used in Python, Rust and C++; Rust adds an _async suffix for the asynchronous form. Request fields are flattened into the wrapper's arguments, which is why each signature below takes the request's fields rather than a request message.

Looking for how something behaves, not what it is called?

The plugin guides explain the semantics - partial transform updates, label tables, time modes - that a field table cannot.
