Struct Item 

pub struct Item {
    pub key: Identifier,
    pub components: DataComponentMap,
    pub craft_remainder: Option<Identifier>,
    pub id: OnceLock<usize>,
}

A Minecraft item type.

Fields

key: Identifier

components: DataComponentMap

craft_remainder: Option<Identifier>

The item key returned when this item is used in crafting (e.g., “bucket” from milk_bucket). Stored as an Identifier to avoid circular reference issues during initialization.

id: OnceLock<usize>

Cached registry ID, set during registration for O(1) lookup on hot paths.

Implementations

impl Item

pub fn from_block(block: BlockRef) -> Self

pub fn from_block_custom_name(_block: BlockRef, name: &'static str) -> Self

pub fn builder_set<T: Component>( self, component: DataComponentType<T>, value: Option<T>, ) -> Self

Builder method to set a component on this item. Used during static initialization.

pub fn get_crafting_remainder(&self) -> ItemStack

Returns the item stack that remains after this item is used in crafting. For example, milk_bucket returns an empty bucket.

pub fn has_tag(&'static self, tag: &Identifier) -> bool

Returns true if this item is tagged with the given tag.
