Struct TransparentObserverSnapshot 

pub struct TransparentObserverSnapshot { /* private fields */ }

A transparent read-only snapshot.

Similar to TransparentObserverMutableSnapshot but for read-only snapshots.

Thread Safety

Contains Cell<T> and RefCell<T> which are not Send/Sync. This is safe because snapshots are stored in thread-local storage and never shared across threads. The Arc is used for cheap cloning within a single thread, not for cross-thread sharing.

Implementations

impl TransparentObserverSnapshot

pub fn new( id: SnapshotId, invalid: SnapshotIdSet, read_observer: Option<ReadObserver>, parent: Option<Weak<TransparentObserverSnapshot>>, ) -> Arc<Self>

pub fn can_reuse(&self) -> bool

Check if this snapshot can be reused for observer changes.

pub fn set_read_observer(&self, _observer: Option<ReadObserver>)

Set the read observer (only allowed if reusable).
