Module filter 

Vector filter operations for integration with the prax query builder.

This module provides filter types that can be used with prax-query’s filter system to perform vector similarity searches as part of WHERE clauses.

Examples

use prax_pgvector::filter::{VectorFilter, VectorOrderBy};
use prax_pgvector::{Embedding, DistanceMetric};

// Create a nearest-neighbor filter
let query_vec = Embedding::new(vec![0.1, 0.2, 0.3]);
let filter = VectorFilter::nearest("embedding", query_vec, DistanceMetric::Cosine, 10);

// Create a distance-filtered search
let query_vec = Embedding::new(vec![0.1, 0.2, 0.3]);
let filter = VectorFilter::within_distance("embedding", query_vec, DistanceMetric::L2, 0.5);
