Struct LifecyclePinRef 

pub struct LifecyclePinRef(/* private fields */);

Cheap-to-clone strong reference to a registered slot’s lifecycle.

Each Clone is a single Arc::clone. Drop releases the keepalive; when the last pin (and the last ImmutableBlock clone) are dropped, the underlying slot transitions to Inactive and may be evicted.

Implementations

impl LifecyclePinRef

pub fn block_id(&self) -> BlockId

pub fn sequence_hash(&self) -> SequenceHash

pub fn manager_id(&self) -> ManagerId

pub fn registration_handle(&self) -> BlockRegistrationHandle

pub fn use_count(&self) -> usize

Strong-count of the underlying Arc<dyn LifecyclePin>. Useful for metrics and tests; do not branch on this in production code.
