The id of the service that the request was sent on.

There can be multiple services that use the built-in ServiceRequest topic. The service_id identifies which service a specific request was sent from.

◆ instance_id

final GUID_t instance_id

Each ServiceRequest is keyed on the instance_id.

The instance_id provides a way for users to differentiate between different requests coming from the same service.

◆ request_body

final ByteSeq request_body

Service-specific information.

Each service uses the request_body field to send information specific to that service in the form of an opaque sequence of bytes. Each service provides a helper function that will deserialize the information from the request body.
