}

Combined size and count figures for a slot table: the table’s own figures, its pending drops and its retained subtrees. Counts are in items and sizes are in bytes.

Fields

group_count: usize

Groups stored in the table.

group_capacity: usize

Groups the group vector holds before it reallocates.

group_record_size: usize

Size of one group record in bytes.

group_heap_bytes: usize

Heap bytes reserved for group records.

payload_count: usize

Payload slots stored across all groups.

payload_capacity: usize

Payload slots the payload store holds before it reallocates.

active_payload_anchor_count: usize

Payload anchors that point at a live payload.

payload_anchor_slot_count: usize

Entries in the payload anchor registry in any state.

detached_payload_anchor_count: usize

Payload anchors whose payload is detached from the table.

invalidated_payload_anchor_count: usize

Payload anchor entries that no longer resolve to a payload.

free_payload_anchor_count: usize

Payload anchor ids free for reuse.

payload_anchor_capacity: usize

Payload anchor entries the registry holds before it reallocates.

payload_anchor_heap_bytes: usize

Heap bytes reserved by the payload anchor registry.

node_count: usize

Nodes stored across all groups.

node_capacity: usize

Nodes the node storage holds before it reallocates.

pending_drop_count: usize

Removed values waiting for their deferred drop.

pending_drop_capacity: usize

Values the pending drop queue holds before it reallocates.

active_anchor_count: usize

Group anchors that point at a live group.

anchor_slot_count: usize

Entries in the group anchor registry in any state.

anchor_sparse_count: usize

Anchor entries kept in the sparse map instead of the dense vector.

detached_anchor_count: usize

Group anchors whose group is detached from the table.

invalidated_anchor_count: usize

Group anchor entries that no longer resolve to a group.

free_anchor_count: usize

Group anchor ids free for reuse.

anchor_capacity: usize

Anchor entries the registry holds before it reallocates.

anchor_heap_bytes: usize

Heap bytes reserved by the group anchor registry.

retained_subtree_count: usize

Subtrees currently retained.

retained_group_count: usize

Groups inside retained subtrees.

retained_payload_count: usize

Payload slots inside retained subtrees.

retained_node_count: usize

Nodes inside retained subtrees.

retained_scope_count: usize

Recompose scopes inside retained subtrees.

retained_anchor_count: usize

Group anchors held by retained subtrees.

retained_heap_bytes: usize

Heap bytes held by retained subtrees.

retained_evictions_total: usize

Subtrees dropped from retention since the composition started.

mutation: SlotTableMutationDebugStats

Counters for subtree moves and index refreshes.
