Struct SnapshotStore 

pub struct SnapshotStore { /* private fields */ }

Bounded, session-owned snapshot and eviction-history storage.

Implementations

impl SnapshotStore

pub const fn new() -> Self

pub fn snapshot_count(&self) -> usize

pub fn path_count(&self) -> usize

pub fn total_bytes(&self) -> usize

pub fn eviction_history_len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn clear(&mut self)

pub fn publish( &mut self, path: impl AsRef<Path>, snapshot: Snapshot, ) -> PublishOutcome

Publish a snapshot. Oversize publication is a no-op: it cannot evict a resident entry, create history, or perturb recency.

pub fn insert( &mut self, path: impl AsRef<Path>, snapshot: Snapshot, ) -> PublishOutcome

Alias emphasizing that publication is the only way to make a snapshot visible to later edits.

pub fn publish_bytes( &mut self, path: impl AsRef<Path>, bytes: &[u8], coverage: CoverageInput, ) -> PublishOutcome

pub fn lookup( &mut self, path: impl AsRef<Path>, tag: &str, ) -> Result<Snapshot, SnapshotLookupError>

pub fn resolve( &mut self, path: impl AsRef<Path>, tag: &str, ) -> Result<Snapshot, SnapshotLookupError>

pub fn lookup_state(&self, path: impl AsRef<Path>, tag: &str) -> SnapshotLookup

pub fn contains(&self, path: impl AsRef<Path>, tag: &str) -> bool

pub fn invalidate_path(&mut self, path: impl AsRef<Path>) -> bool

Remove a path because its lifecycle ended (for example, an MV source). Lifecycle invalidation is intentionally not an eviction and therefore must not create an eviction-history record.

pub fn remove_path(&mut self, path: impl AsRef<Path>) -> bool

pub fn eviction_history_contains( &self, path: impl AsRef<Path>, tag: &str, ) -> bool

pub fn iter(&self) -> impl Iterator<Item = (&Path, &Snapshot)>

Trait Implementations

impl Clone for SnapshotStore

fn clone(&self) -> SnapshotStore

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SnapshotStore

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SnapshotStore

fn default() -> SnapshotStore

Returns the “default value” for a type.
