Struct BruteForceBackend 

pub struct BruteForceBackend { /* private fields */ }

A brute-force search backend that computes cosine similarity against every stored vector on each query.

Dimension locking

The first non-empty call to ingest locks the dimension. Subsequent calls with a different dimension return Err(BackendError::Adapter("dimension mismatch: expected {d}, got {got}")).

Python parity

• Overwriting an existing id is silent (matches Python dict[id] = vec).
• remove with unknown ids is a no-op (matches Python dict.pop(id, None)).

Implementations

impl BruteForceBackend

pub fn new() -> Self

Create a new, empty backend.

Trait Implementations

impl Default for BruteForceBackend

fn default() -> Self

Returns the “default value” for a type.

impl SearchBackend for BruteForceBackend

fn ingest( &mut self, vectors: &[(VectorId, Vec<f32>)], ) -> Result<(), BackendError>

Store the supplied (VectorId, Vec<f32>) pairs.

fn search( &self, query: &[f32], top_k: usize, ) -> Result<Vec<SearchResult>, BackendError>

Return the top_k nearest vectors to query by cosine similarity, sorted descending.

fn remove(&mut self, vector_ids: &[VectorId]) -> Result<(), BackendError>

Remove vectors by id.

fn len(&self) -> usize

Number of vectors currently stored.

fn dim(&self) -> Option<usize>

The locked dimension, or None if no vectors have been ingested yet.

fn is_empty(&self) -> bool

Returns true if no vectors are stored.
