Enum Metric 

pub enum Metric {
    Cosine,
    L2,
    Dot,
}

Distance function of a collection. For every metric, smaller is closer.

Variants

Cosine

1 - cos(a, b). Vectors are normalized when they are stored.

L2

Squared Euclidean distance.

Dot

Negative inner product.

Implementations

impl Metric

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

pub fn distance(self, a: &[f32], b: &[f32]) -> f32
