Enum Similarity 

pub enum Similarity {
    Cosine,
    Dot,
    Euclidean,
}

Immutable vector-space contract bound through stable aliases.

Variants

Cosine

Cosine similarity (dot product of L2-normalized vectors).

Dot

Dot product (raw; for best results use normalized vectors).

Euclidean

Euclidean similarity = 1 / (1 + euclidean_distance) (Neo4j-style).

Implementations

impl Similarity

pub fn as_str(&self) -> &'static str
