Implementations

impl ItemRegistry

pub fn new() -> Self

pub fn register(&mut self, item: ItemRef) -> usize

pub fn register_block_item(&mut self, block: BlockRef, item: ItemRef)

Registers the vanilla BlockItem association used by Block.asItem().

pub fn is_block_item(&self, item: ItemRef) -> bool

Returns whether this item is Vanilla’s BlockItem or one of its subclasses.

BlockItem construction registers its block-to-item association, so the extracted association is also the complete class-hierarchy capability.

pub fn by_block(&self, block: BlockRef) -> ItemRef

Returns the item associated with this block, or air when it has no block item.

Vanilla equivalent: Item.byBlock(Block) / Block.asItem().

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