Struct SemanticCacheCore 

pub struct SemanticCacheCore { /* private fields */ }

Pure cache bookkeeping (no embedder, no retriever — fully unit-testable).

Implementations

impl SemanticCacheCore

pub fn new(config: SemanticCacheConfig) -> Self

Creates a core with the given config.

pub fn len(&self) -> usize

Number of live entries.

pub fn is_empty(&self) -> bool

Whether the cache is empty.

pub fn lookup( &self, query: &str, query_vector: Option<&[f32]>, k: usize, now: Instant, ) -> Option<(Vec<SearchResult>, CacheHitKind)>

Looks up query (optionally with its embedding for semantic matching) for result sets of size k. Returns the cached results and the hit kind.

query_vector should be the freshly embedded query; pass None to restrict to lexical hits only.

pub fn insert( &self, query: &str, query_vector: Vec<f32>, k: usize, results: Vec<SearchResult>, now: Instant, )

Inserts a result set for (query, k).

pub fn invalidate(&self)

Clears all entries (corpus update invalidation).

Trait Implementations

impl Debug for SemanticCacheCore

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

Formats the value using the given formatter.
