Struct Ingredient 

pub struct Ingredient {
    pub items: HashSet<String>,
    pub order: Vec<String>,
    pub custom: Option<(String, BTreeMap<JavaString, Tag>)>,
    pub children: Option<(Shape, Vec<Ingredient>)>,
}

A set of accepted items (expanded from an item, list or tag), and the items in its HolderSet order (Ingredient.display’s TagSlotDisplay).

Fields

items: HashSet<String>

The items it accepts, however the source shape named them.

order: Vec<String>

The same items in HolderSet order (display).

custom: Option<(String, BTreeMap<JavaString, Tag>)>

A mod’s own kind, for matching at craft time: the kind and its NBT compound, as the load-time hook saw them (ingredient_test).

children: Option<(Shape, Vec<Ingredient>)>

NeoForge’s shapes, with their children parsed: matching a concrete stack asks each child its own test (a mod’s kind among them), as on NeoForge — the flat list above only names items.

Implementations

impl Ingredient

pub fn item_keys( &self, host: &dyn Host, ) -> Result<Arc<[ItemKey]>, IngredientKeysError>

Resolve exact membership once per load/reload for local matching in mod memory. Plain item lists, expanded tags and standard shapes with no custom descendants are component-independent. A custom/component predicate anywhere in the tree returns NotEnumerable: the display item list is not an exact predicate (and for differences containing custom predicates is not even necessarily a superset). Such predicates remain mod-owned; this method never invokes a match-time hook. One host call per ingredient at publication; never call this per tick or candidate.

pub fn of(items: Vec<String>) -> Ingredient

The items of a list, in order.

pub fn test(&self, host: &dyn Host, stack: &ItemStack) -> bool

Ingredient.test: whether stack fits: a stack the list names, and for a mod’s own kind one the match-time hook accepts (ICustomIngredient.test). The game answers with the loop context of the side host runs on; a host without a game refuses every stack.
