Struct PreparedTRAStarWaypointDatabaseFixedDemotionRule 

pub struct PreparedTRAStarWaypointDatabaseFixedDemotionRule { /* private fields */ }

Prepared TRA* that demotes protected midpoints under a fixed overflow policy.

Protected overflow evicts the least-recent protected entry rather than demoting to probation.

Implementations

impl PreparedTRAStarWaypointDatabaseFixedDemotionRule

pub fn builder() -> TRAStarWaypointDatabaseFixedDemotionRuleBuilder

Returns a TRAStarWaypointDatabaseFixedDemotionRuleBuilder for preprocess entry.

pub fn prepared_tra_star(&self) -> &PreparedTRAStar

Underlying base TRA* prepared surface.

pub fn admission_cost_threshold(&self) -> f64

Minimum portal segment cost required to retain a midpoint in cache.

pub fn promotion_hits_required(&self) -> usize

Probation hits required before promoting into the protected tier.

pub fn eviction_capacity(&self) -> usize

Total midpoint capacity before eviction.

pub fn protected_segment_capacity(&self) -> usize

Capacity reserved for the protected segment.

pub fn retained_waypoint_count(&self) -> usize

Midpoints currently retained under the demotion rule.

pub fn retained_probation_count(&self) -> usize

Midpoints currently in probation.

pub fn retained_protected_count(&self) -> usize

Midpoints currently in the protected segment.

pub fn search(&self, query: NavmeshQuery) -> NavmeshSearchResult

Routes while applying fixed demotion on protected overflow.
