Struct PointOfInterestSet 

pub struct PointOfInterestSet {
    pois_by_pos: FxHashMap<PackedSectionBlockPos, PointOfInterest>,
    pois_by_type: FxHashMap<usize, FxHashSet<PackedSectionBlockPos>>,
    dirty: bool,
}

Stores all POIs within a single chunk section (16x16x16).

Uses a section-relative packed block position as the key, with a secondary index by POI type for type-filtered queries.

Fields

pois_by_pos: FxHashMap<PackedSectionBlockPos, PointOfInterest>

pois_by_type: FxHashMap<usize, FxHashSet<PackedSectionBlockPos>>

dirty: bool

Implementations

impl PointOfInterestSet

pub fn new() -> Self

Creates an empty POI set.

pub fn add( &mut self, packed_pos: PackedSectionBlockPos, poi: PointOfInterest, ) -> Option<&PointOfInterest>

Returns a reference to the inserted POI, or None if one already exists at that position.

pub fn remove( &mut self, packed_pos: PackedSectionBlockPos, ) -> Option<PointOfInterest>

Removes and returns the POI at the given packed position, if present.

pub fn get(&self, packed_pos: PackedSectionBlockPos) -> Option<&PointOfInterest>

Returns a reference to the POI at the given packed position.

pub fn get_mut( &mut self, packed_pos: PackedSectionBlockPos, ) -> Option<&mut PointOfInterest>

Returns a mutable reference to the POI at the given packed position.

pub fn get_by_type( &self, type_id: usize, status: OccupationStatus, max_tickets: u32, ) -> Vec<&PointOfInterest>

Returns all POIs of the given type matching the occupation status.

pub fn get_matching( &self, type_predicate: &impl Fn(usize) -> bool, status: OccupationStatus, max_tickets_fn: &impl Fn(usize) -> u32, ) -> Vec<&PointOfInterest>

Returns all POIs matching the type predicate and occupation status.

pub const fn is_dirty(&self) -> bool

Returns true if any POIs have been added or removed since last cleared.

pub const fn clear_dirty(&mut self)

Clears the dirty flag.

pub fn is_empty(&self) -> bool

Returns true if this set contains no POIs.

pub fn len(&self) -> usize

Returns the number of POIs in this set.

pub fn iter( &self, ) -> impl Iterator<Item = (PackedSectionBlockPos, &PointOfInterest)>

Iterates over all POIs in this set as (packed_pos, poi) pairs.

Trait Implementations

impl Default for PointOfInterestSet

fn default() -> Self

Returns the “default value” for a type.
