Struct GcPassEvent 

pub struct GcPassEvent {
    pub trigger: GcTrigger,
    pub stats: GcStats,
    pub registry_len_before: usize,
    pub duration_ns: u64,
}

One collector pass, as reported to the set_gc_observer observer. Fires for every pass that actually ran — including aborted ones (visible via stats.aborted) and prune-only fast passes — but never for a maybe_collect that stayed below the threshold.

Fields

trigger: GcTrigger

The safe point that requested the pass.

stats: GcStats

The pass’s result.

registry_len_before: usize

Registry length (live + not-yet-pruned dead entries) when the pass started.

duration_ns: u64

Wall-clock duration of the pass. Zero on wasm32 (no monotonic clock).
