Struct DefectGraphBuilder 

pub struct DefectGraphBuilder { /* private fields */ }

Spatial-hash-accelerated defect graph for efficient neighbor queries.

Defects are binned into cells of side cell_size. Neighbor lookups scan only the O(1) adjacent cells, giving expected O(1) query time for sparse defect densities (which is the regime of interest below threshold).

Implementations

impl DefectGraphBuilder

pub fn new(cell_size: u32) -> Self

pub fn build(&self, syndrome: &SyndromeData, max_radius: u32) -> Vec<DefectEdge>

Build a defect graph using spatial hashing for O(1) neighbor lookup.

Returns edges connecting each defect to its nearest neighbors within max_radius Manhattan distance.
