Struct InMemoryStore 

#[non_exhaustive]
pub struct InMemoryStore { /* private fields */ }

HashMap-based VectorStore implementation for tests.

Performs brute-force cosine similarity search — no HNSW required. save and load are no-ops. is_ready is configurable.

Implementations

impl InMemoryStore

pub fn new(dimensions: usize) -> Self

Create a new InMemoryStore with the given embedding dimensionality.

is_ready defaults to true. Use InMemoryStore::with_ready to override.

pub fn with_ready(self, ready: bool) -> Self

Override the value returned by is_ready().

Trait Implementations

impl VectorStore for InMemoryStore

fn add( &self, scope: &Scope, vector: &[f32], qualified_name: String, ) -> Result<u64, MemoryError>

Insert or upsert vector for qualified_name in the given scope.

fn remove( &self, _scope: &Scope, qualified_name: &str, ) -> Result<(), MemoryError>

Remove the entry for qualified_name from scope (and from the all-index). Best-effort — does not fail if the entry is absent.

fn search( &self, filter: &ScopeFilter, query: &[f32], limit: usize, ) -> Result<Vec<(u64, String, f32)>, MemoryError>

Search for the limit nearest neighbours of query, filtered by filter.

fn find_by_name(&self, qualified_name: &str) -> Option<u64>

Look up the vector key for a qualified name in the all-index.

fn save(&self, _dir: &Path) -> Result<(), MemoryError>

Persist all indexes to subdirectories under dir.

fn is_ready(&self) -> bool

Returns true when the store is ready to accept queries.

fn dimensions(&self) -> usize

The embedding dimensionality this store was initialised with.

fn commit_sha(&self) -> Option<String>

The commit SHA last written to or read from the index metadata, if any.

fn set_commit_sha(&self, sha: Option<&str>)

Overwrite the stored commit SHA.
