Enum Metric 

pub enum Metric {
    Angular,
    Euclidean,
}

Distance a graph is built and searched for.

Variants

Angular

Cosine: rows are normalized at build, queries need not be.

Euclidean

Squared Euclidean distance on the rows as given. Construction scores |a|^2 + |b|^2 - 2 <a, b> with exact per-row squared norms; the vertex index orders candidates by |x|^2 / 2 - <q, x - mean>, its code estimate of the same order. The edge index (QGraph), the screen and the neighbour blocks are angular only.
