Struct VectorIndex 

pub struct VectorIndex { /* private fields */ }

Thread-safe handle to a vector index.

Implementations

impl VectorIndex

pub fn new(config: VectorIndexConfig) -> Result<Self, MemoryError>

Construct a new index from a config. Dispatches to the active backend (selected at compile time via feature flag).

pub fn load( dir: &Path, basename: &str, config: VectorIndexConfig, ) -> Result<Self, MemoryError>

Load a previously saved index. Dispatches to the active backend.

pub fn insert(&self, key: String, vector: &[f32]) -> Result<(), MemoryError>

pub fn delete(&self, key: &str) -> Result<(), MemoryError>

pub fn update(&self, key: String, vector: &[f32]) -> Result<(), MemoryError>

pub fn search( &self, query: &[f32], top_k: usize, ) -> Result<Vec<VectorHit>, MemoryError>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn save(&self, dir: &Path, basename: &str) -> Result<(), MemoryError>

pub fn backend_name(&self) -> &'static str

pub fn _placeholder(&self)

Note: downcasting to a concrete backend type is not supported through the trait. Tests that need backend-specific introspection should use the backend_name() method or read the sidecar manifest. This is intentional — keeping the trait free of Any avoids the vtable overhead and keeps the public surface minimal.

Trait Implementations

impl Clone for VectorIndex

fn clone(&self) -> VectorIndex

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
