Struct SubgoalGraphBuilder 

pub struct SubgoalGraphBuilder;

PreprocessedGridBuilder for sparse corner subgoal graphs.

Uniform hop cost only (traversal_cost == 1). Correctness-first foundation with online A* fallback when the subgoal set is empty, large, or abstract search fails. Prefer as a multi-query experiment baseline, not a large-map acceleration claim.

Implementations

impl SubgoalGraphBuilder

pub const fn new() -> Self
