Struct StructureReferenceSet 

pub struct StructureReferenceSet {
    insertion_order: Vec<ChunkPos>,
    iteration_order: Vec<ChunkPos>,
}

Set of structure-start chunk positions with vanilla iteration order.

Reference generation discovers sources in a stable scan order, but vanilla stores the packed chunk longs in fastutil’s LongOpenHashSet. Feature-stage placement consumes the set through that table iteration order, so Steel keeps the insertion order for persistence and exposes the vanilla iteration order for worldgen.

Fields

insertion_order: Vec<ChunkPos>

iteration_order: Vec<ChunkPos>

Implementations

impl StructureReferenceSet

pub fn insert(&mut self, pos: ChunkPos) -> bool

Inserts a chunk position if it was not already present.

pub fn extend(&mut self, positions: impl IntoIterator<Item = ChunkPos>)

Extends this set with insertion-order duplicate removal.

pub fn iter(&self) -> Iter<'_, ChunkPos>

Returns an iterator over positions in vanilla LongOpenHashSet order.

pub fn insertion_order_iter(&self) -> Iter<'_, ChunkPos>

Returns an iterator over positions in discovery order.

pub const fn is_empty(&self) -> bool

Returns true when no positions are stored.

fn rebuild_iteration_order(&mut self)

fn vanilla_long_open_hash_set_order( insertion_order: &[ChunkPos], ) -> Vec<ChunkPos>

fn vanilla_long_open_hash_set_table_size(len: usize) -> Option<usize>
