Struct VectorStore 

pub struct VectorStore { /* private fields */ }

In-memory vector store partitioned by namespace.

Implementations

impl VectorStore

pub fn new() -> Self

Create an empty store without a fixed dimension.

pub fn with_dimension(dim: usize) -> Self

Create an empty store that enforces a fixed dimension on upsert.

pub fn upsert(&mut self, entry: VectorEntry) -> Result<bool, StoreError>

Insert or update a vector entry.

Returns Ok(true) if the entry was newly inserted, Ok(false) if an existing entry with the same (namespace, id) was replaced.

When the store is dimension-aware (created with VectorStore::with_dimension), vectors of a different length are rejected.

pub fn delete(&mut self, namespace: &str, id: &str) -> bool

Delete the entry with the given (namespace, id).

Returns true if the entry existed and was removed.

pub fn get(&self, namespace: &str, id: &str) -> Option<&VectorEntry>

Look up a specific entry by (namespace, id).

pub fn contains(&self, namespace: &str, id: &str) -> bool

Check whether a specific (namespace, id) exists.

pub fn search( &self, namespace: &str, query: &[f32], top_k: usize, ) -> Vec<SearchResult>

Return the top_k most-similar entries in namespace to query, sorted by descending cosine similarity.

pub fn search_all_namespaces( &self, query: &[f32], top_k: usize, ) -> Vec<SearchResult>

Return the top_k most-similar entries across all namespaces.

pub fn list(&self, namespace: &str) -> Vec<&VectorEntry>

List all entries in namespace. Returns an empty slice if the namespace does not exist.

pub fn delete_namespace(&mut self, namespace: &str) -> usize

Remove all entries belonging to namespace.

Returns the number of entries that were deleted.

pub fn stats(&self) -> VectorStoreStats

Return aggregate statistics about the store.

Trait Implementations

impl Default for VectorStore

fn default() -> Self

Returns the “default value” for a type.
