Struct HddsWriterListener 

#[repr(C)]
pub struct HddsWriterListener {
    pub on_sample_written: HddsOnSampleWritten,
    pub on_publication_matched: HddsOnPublicationMatched,
    pub on_offered_deadline_missed: HddsOnOfferedDeadlineMissed,
    pub on_offered_incompatible_qos: HddsOnOfferedIncompatibleQos,
    pub on_liveliness_lost: HddsOnLivelinessLost,
    pub user_data: *mut c_void,
}

C-compatible DataWriter listener.

Set callback fields to receive events. Any callback set to None (NULL) will be silently ignored. The user_data pointer is passed through to every callback invocation.

Example (C)

HddsWriterListener listener = {0};
listener.on_publication_matched = my_match_callback;
listener.user_data = my_context;
hdds_writer_set_listener(writer, &listener);
