Struct rmw_matched_status_t 

#[repr(C)]
pub struct rmw_matched_status_t {
    pub total_count: u32,
    pub total_count_change: u32,
    pub current_count: u32,
    pub current_count_change: i32,
}

Matched payload — NROS_RMW_EVENT_PUBLICATION_MATCHED / NROS_RMW_EVENT_SUBSCRIPTION_MATCHED. Upstream rmw_matched_status_t (Iron+), same four fields in the same order.

Width is the one deviation: upstream’s three counts are size_t; ours are uint32_t, like every other count in this header, so the union keeps one layout on 32- and 64-bit targets. current_count_change is int32_t on both sides.

Fields

total_count: u32

Cumulative matches over the entity’s lifetime.

total_count_change: u32

Change in total_count since the last report.

current_count: u32

Endpoints matched RIGHT NOW.

current_count_change: i32

Change in current_count since the last report; negative when an endpoint left.
