Fields

slots: Vec<Box<dyn Any>>

slot_callers: Vec<&'static Location<'static>>

cursor: usize

auto_counts: FxHashMap<String, usize>

keyed_slots: FxHashMap<String, Box<dyn Any>>

keyed_owner: FxHashMap<String, String>

keyed_owners: FxHashMap<String, FxHashSet<String>>

live_keyed_owners: FxHashSet<String>

Owner tokens of registered scopes visited this frame, plus the root token.

live_keyed_keys: FxHashSet<String>

Raw keys read through remember_with_key this frame.

cache_preserved_owners: FxHashSet<String>

Owner tokens of scopes served from cache this frame. Their bodies did not re-run, so their keyed slots go unread and must not be collected.

scope_caches: FxHashMap<String, ScopeCache>

live_scope_keys: FxHashSet<String>
