Struct HyperbolicRegion 

pub struct HyperbolicRegion { /* private fields */ }

Hyperbolic region in the Poincaré disk.

A region in hyperbolic space, used for locality-sensitive hashing.

Implementations

impl HyperbolicRegion

pub fn new(center: HyperbolicPoint, radius: FixedPoint) -> Self

Create a new hyperbolic region.

pub fn contains( &self, point: &HyperbolicPoint, _poincare_disk: &PoincareDisk, ) -> bool

Check if a point is contained in this region.

Compares in SQUARED-ratio proxy space: d <= radius is exactly r²(d) <= r²(radius) (both transforms strictly monotone), and the proxy needs one dot product against the cached center norm instead of the exact kernel’s sqrt + atanh (~32 us -> ~1 us per check). find_bucket walks every bucket through this on a containment miss, which made it 86% of insert cost before the proxy.

pub fn center(&self) -> &HyperbolicPoint

Get the center of the region.

pub fn radius(&self) -> FixedPoint

Get the radius of the region.

pub fn validation_mask(&self) -> &FixedVector

Get the validation mask.

pub fn quick_validate(&self, point: &HyperbolicPoint) -> bool

Quick validation check against a point. Uses a generous threshold (positive similarity) as a fast heuristic.
