Implementations

impl InventoryType

pub fn protocol_id(&self) -> i32

Returns the Minecraft protocol VarInt ID for this inventory type.

Used when encoding the OpenWindow packet. IDs correspond to the 1.21.4 protocol (0 = generic_9x1 through 24 = stonecutter).

pub fn slot_count(&self) -> usize

Returns the number of container slots this type has.

Does not include the player inventory slots that are appended when the window is opened.

pub fn is_chest_like(&self) -> bool

Returns true if this is a generic chest-like inventory (9xN) or a shulker box.

Chest-like inventories have simple slot layouts where every slot behaves the same (no special output slot, no fuel/product slots).

pub fn has_craft_output(&self) -> bool

Returns true if this inventory has a special crafting output slot at index 0.

Currently only Crafting returns true. The output slot is server-computed from the crafting grid contents.
