hbp_nrp_simserver.server package

This is package contains the Simulation server. It runs user-defined python scripts that use an nrp_core.client.NRPCore.

A simulation server can be managed by an instance of SimulationServerInstance and once initialized it sends, on MQTT topics, information about its status (/status) and, on error, a message describing such error (/runtime_error).

The runtime state of the server is controlled via an instance of SimulationLifecycle that reacts to state changes initiated by the user via the REST API exposed by hbp_nrp_backend.server. Besides those, state changes initiated by the Simulation server are the ones that depend on the simulation being run, i.e. ‘completed’ and ‘failed’.
