Struct CraftingInput 

pub struct CraftingInput {
    pub width: usize,
    pub height: usize,
    pub items: Vec<ItemStack>,
    ingredient_count: usize,
}

Represents the current state of a crafting grid.

This should be a positioned (trimmed) input - containing only the bounding box of non-empty items. Use CraftingInput::positioned() to create one from raw grid slots.

Fields

width: usize

height: usize

items: Vec<ItemStack>

Items in row-major order (width * height).

ingredient_count: usize

Pre-computed count of non-empty items.

Implementations

impl CraftingInput

pub const EMPTY: CraftingInput

An empty crafting input.

pub fn new(width: usize, height: usize, items: Vec<ItemStack>) -> Self

Creates a new crafting input, pre-computing ingredient count.

pub fn positioned( width: usize, height: usize, items: Vec<ItemStack>, ) -> PositionedCraftingInput

Creates a positioned (trimmed) crafting input from raw grid slots.

This is the main entry point matching Java’s CraftingInput.ofPositioned(). Returns the trimmed input along with the offset from the original grid.

pub fn get(&self, x: usize, y: usize) -> &ItemStack

Gets the item at the specified position.

pub fn ingredient_count(&self) -> usize

Returns the number of non-empty items (pre-computed).

pub fn is_empty(&self) -> bool

Returns true if the input is empty.

Trait Implementations

impl Clone for CraftingInput

fn clone(&self) -> CraftingInput

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CraftingInput

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
