Implementations

impl ItemStack

pub fn new(item: Item, count: i32) -> Self

Create a new ItemStack with the given number of [Item]s.

If item is air or the count isn’t positive, then it’ll be set to an empty ItemStack.

pub fn is_empty(&self) -> bool

Check if the slot is ItemStack::Empty, if the count is <= 0, or if the item is air.

This is the opposite of ItemStack::is_present.

pub fn is_present(&self) -> bool

Check if the slot is not ItemStack::Empty, if the count is > 0, and if the item is not air.

This is the opposite of ItemStack::is_empty.

pub fn count(&self) -> i32

Return the amount of the item in the slot, or 0 if the slot is empty.

Note that it’s possible for the count to be zero or negative when the slot is present.

pub fn split(&mut self, count: u32) -> ItemStack

Remove count items from this slot, returning the removed items.

pub fn kind(&self) -> Item

Get the kind of the item in this slot, or [azalea_registry::Item::Air]

pub fn update_empty(&mut self)

Update whether this slot is empty, based on the count.

pub fn as_present(&self) -> Option<&ItemStackData>

Convert this slot into an ItemStackData, if it’s present.

pub fn as_present_mut(&mut self) -> Option<&mut ItemStackData>

pub fn get_component<'a, T: DataComponent>(&'a self) -> Option<Cow<'a, T>>

Get the value of a data component for this item.

This is used for things like getting the damage of an item, or seeing how much food it replenishes.

Trait Implementations

impl AzaleaRead for ItemStack

fn azalea_read(buf: &mut Cursor<&[u8]>) -> Result<Self, BufReadError>

impl AzaleaWrite for ItemStack

fn azalea_write(&self, buf: &mut impl Write) -> Result<()>

impl Clone for ItemStack

fn clone(&self) -> ItemStack

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ItemStack

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

Formats the value using the given formatter.

impl Default for ItemStack

fn default() -> ItemStack

Returns the “default value” for a type.

impl From<(Item, i32)> for ItemStack

fn from(item: (Item, i32)) -> Self

Converts to this type from the input type.

impl From<Item> for ItemStack

fn from(item: Item) -> Self

Converts to this type from the input type.

impl From<ItemStackData> for ItemStack

fn from(item: ItemStackData) -> Self

Converts to this type from the input type.

impl PartialEq for ItemStack

fn eq(&self, other: &ItemStack) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
