Enum Metric 

pub enum Metric {
    L2,
    Cosine,
    Ip,
    Hamming,
}

How a vector is compared. Part of the shape because a collection built for cosine and searched as if it were L2 gives wrong answers quietly.

Variants

L2

Euclidean distance.

Cosine

Cosine similarity.

Ip

Inner product.

Hamming

Hamming distance, for binary vectors.
