Module types 

Core types for vector storage.

This module provides the fundamental types for vector embedding storage:

Entity-based embeddings

• Embedding - A validated dense vector embedding with dimension checks
• SparseEmbedding - A sparse vector embedding (index, value pairs)
• MultiVectorEmbedding - A multi-vector embedding (ColBERT-style token embeddings)
• BinaryEmbedding - A binary vector embedding (bit-packed for Hamming distance)
• EmbeddingName - A named embedding space identifier
• EmbeddingSpace - Metadata about an embedding space (dimension, distance metric)
• SparseEmbeddingSpace - Metadata about a sparse embedding space
• MultiVectorEmbeddingSpace - Metadata about a multi-vector embedding space
• BinaryEmbeddingSpace - Metadata about a binary embedding space

Separated vector storage

• VectorData - Vector data supporting dense, sparse, multi-vector, and binary formats
• VectorRef - Reference to a vector attached to an entity

Point collections (Qdrant-style)

• Collection - A named collection of points with a defined schema
• CollectionName - A validated collection name
• CollectionSchema - Schema defining the vectors in a collection
• VectorConfig - Configuration for a named vector (type, dimension)
• VectorName - A validated vector name
• Payload - JSON payload attached to a point
• NamedVector - A vector value (dense, sparse, or multi-vector)
