Struct CoreShared 

pub struct CoreShared { /* private fields */ }

Core-global state with NO per-scheduling-group partition (Slice B-2 Step 1, D220-EXEC). Hoisted out of CoreState so that when Step 2 shards nodes/children per ShardKey, THESE remain singular: monotonic id counters, the topology-sink registry, the cross-shard-visible currently_firing reentrancy stack (P13 / /qa F2 — the load-bearing cross-thread-visibility property), the two Core-global caps, and the Core-shutdown scratch-release queue.

Step 1 (this stage): behaviour-identical. A plain sub-struct of CoreState under the SAME single cell/lock — s.shared.<f> is exactly the old s.<f>. Step 2 reshapes [crate::state_cell] to hold one CoreShared + a per-ShardKey shard map; pure-shared ops then take only the shared guard (with_shared), shard ops the shard guard (with_shard), and when both are needed the deadlock-free rule is shard guard OUTER, shared guard INNER (D220-EXEC).

Trait Implementations

impl Drop for CoreShared

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
