Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

L2SqrtExpanded

L2 distance with square root.

CosineExpanded

Cosine distance.

L1

L1 (Manhattan) distance.

L2Unexpanded

L2 distance (unexpanded form).

L2SqrtUnexpanded

L2 distance with square root (unexpanded form).

InnerProduct

Inner product.

Linf

Chebyshev (L-infinity) distance.

Canberra

Canberra distance.

LpUnexpanded(f32)

Generalized Minkowski (Lp) distance with exponent p.
