Struct PoiTypeRegistry 

pub struct PoiTypeRegistry {
    types_by_id: Vec<PoiTypeRef>,
    types_by_key: FxHashMap<Identifier, usize>,
    state_to_type: FxHashMap<BlockStateId, usize>,
    tags: RegistryTags,
    allows_registering: bool,
}

Registry of all POI types, with reverse lookup from block state to type.

Fields

types_by_id: Vec<PoiTypeRef>

types_by_key: FxHashMap<Identifier, usize>

state_to_type: FxHashMap<BlockStateId, usize>

O(1) block state -> POI type ID lookup.

tags: RegistryTags

allows_registering: bool

Implementations

impl PoiTypeRegistry

pub fn new() -> Self

pub fn register(&mut self, poi_type: PoiTypeRef) -> usize

pub fn build_state_index(&mut self, blocks: &BlockRegistry)

Expands every registered POI type’s block matchers into the state -> type lookup map. Must be called once after the block registry is fully populated, since resolving matchers to state ids requires the block registry.

pub fn type_for_state(&self, state_id: BlockStateId) -> Option<PoiTypeRef>

pub fn type_id_for_state(&self, state_id: BlockStateId) -> Option<usize>

pub fn is_poi_state(&self, state_id: BlockStateId) -> bool

pub fn iter(&self) -> impl Iterator<Item = (usize, PoiTypeRef)> + '_
