Module rmw_liveliness_kind_t

Constants§

NROS_RMW_LIVELINESS_AUTOMATIC: Backend’s keepalive task asserts liveliness automatically.
NROS_RMW_LIVELINESS_MANUAL_BY_NODE: Application calls assert_liveliness() at the node level.
NROS_RMW_LIVELINESS_MANUAL_BY_TOPIC: Application calls assert_liveliness() per topic explicitly.
NROS_RMW_LIVELINESS_SYSTEM_DEFAULT: Let the middleware choose. Spelled NONE before W5/B2 and used the same way: nothing is asserted and nothing is tracked. Upstream has no separate NONE, so the two collapse onto value 0.
NROS_RMW_LIVELINESS_UNKNOWN: The backend could not determine this policy.
