Detailed Description

serviceEventInfo is a structured value type usable in QML. It maps directly to the service_msgs::msg::ServiceEventInfo ROS 2 message type.

Construct a serviceEventInfo in QML by assigning a JavaScript object whose keys are its component properties, or by setting those properties individually.

Property Documentation

clientGid : list<uint8_t>

Unique identifier for the client that sent the service request

Note, this is only unique for the current session. The size here has to match the size of rmw_dds_common/msg/Gid, but unfortunately we cannot use that message directly due to a circular dependency.

eventType : uint8_t

The type of event this message represents

sequenceNumber : int64_t

Sequence number for the request

Combined with the client ID, this creates a unique ID for the service transaction

stamp : time

Timestamp for when the event occurred (sent or received time)
