Struct InMemoryVectorStore 

pub struct InMemoryVectorStore { /* private fields */ }

In-memory vector store backed by a simple Vec with linear scan search.

Intended for unit tests and prototyping — not suitable for production workloads.

Implementations

impl InMemoryVectorStore

pub fn new() -> Self

Create a new empty in-memory vector store.

pub fn with_metric(default_metric: SimilarityMetric) -> Self

Create a new empty in-memory vector store with the metric used for new collections.

pub fn with_options( default_metric: SimilarityMetric, limits: VectorStoreLimits, ) -> Self

Create a new empty in-memory vector store with explicit safety limits.

Trait Implementations

impl Default for InMemoryVectorStore

fn default() -> Self

Returns the “default value” for a type.
