Interface VectorSimilarityFunctions

public interface VectorSimilarityFunctions

Utility interface providing vector similarity functions.

MethodHandles are returned to avoid a static reference to MemorySegment, which is not in the currently lowest compile version, JDK 17. Code consuming the method handles will, by definition, require access to MemorySegment.
