Detailed Description

State pointed to by rmw_publisher_t::data.

Bundles the DDS DataWriter, its Topic, and the cached introspection handle so rmw_publish() can serialize without re-resolving the type support.

variable gid

16-byte publisher GID.

uint8_t AstuteDDSPublisher::gid[16];

variable listener_mtx

std::mutex AstuteDDSPublisher::listener_mtx;

Protects every on_*_cb / on_*_ud pair below against concurrent rmw_event_set_callback calls racing the AstuteDDS listener thread. AstuteDDS's astutedds_datawriter_set_listener() replaces the whole listener struct on each call, so every event callback setter must hold this mutex and call rebuild_publisher_listener() (see listener.hpp) to reassemble the full struct from current state rather than clobbering previously-registered callbacks.
