Struct InMemorySnapshotStore 

pub struct InMemorySnapshotStore { /* private fields */ }

In-memory SnapshotStore backed by lru. Per-path history is a short ring of full-file versions (oldest dropped first); per-session path tracking is LRU-bounded so cold paths age out automatically.

Recording byte-identical content again refreshes recency and reuses the existing tag (read fusion); recording new content unshifts a fresh version onto the front of the path history.

Implementations

impl InMemorySnapshotStore

pub fn new() -> Self

Build a store with the default limits (30 paths × 4 versions × 64 MiB).

pub fn with_options(opts: InMemorySnapshotStoreOptions) -> Self

Build a store with custom limits.

Trait Implementations

impl Debug for InMemorySnapshotStore

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

Formats the value using the given formatter.

impl Default for InMemorySnapshotStore

fn default() -> Self

Returns the “default value” for a type.

impl SnapshotStore for InMemorySnapshotStore

fn head(&self, path: &str) -> Option<Snapshot>

Most-recently recorded version for path, or None if none.

fn by_hash(&self, path: &str, hash: &str) -> Option<Snapshot>

Recorded version for path whose tag equals hash, or None.

fn record( &self, path: &str, full_text: &str, seen_lines: Option<&[u32]>, ) -> String

Record the full normalized text of path and return its content tag. seen_lines (optional) are the 1-indexed lines the producer displayed; they merge into Snapshot::seen_lines across reads of identical text.

fn record_seen_lines(&self, path: &str, hash: &str, lines: &[u32])

Merge lines into the Snapshot::seen_lines of the version whose tag equals hash. No-op when no such version is retained.

fn invalidate(&self, path: &str)

Drop the version history for a single path.

fn clear(&self)

Drop every version history.
