Struct Stack 

pub struct Stack {
    pub id: i32,
    pub count: i32,
    pub damage: i16,
    pub nbt: Option<RawNbt>,
}

A non-empty item stack as the client holds it.

count is a Java int in vanilla (sent as a byte). 1.8 keeps stacks with a count of zero or less as real stacks (they render as a red “0”); 1.16.5 treats them as empty, so a 1.16.5 Inventory never stores one.

Fields

id: i32

Numeric item id (1.8: legacy id; 1.16.5: item registry id).

count: i32

Stack size.

damage: i16

1.8 damage / metadata. Always 0 on 1.16.5 (damage lives in the Damage NBT tag).

nbt: Option<RawNbt>

Item NBT exactly as received, if any.

Implementations

impl Stack

pub fn new(id: i32, count: i32, damage: i16) -> Stack

A stack without NBT.

pub fn with_count(&self, count: i32) -> Stack

The same item (id, damage, NBT) with another count.

pub fn from_legacy(s: ItemStack) -> Stack

Converts a 1.8 wire stack.

pub fn from_modern(s: ItemStack) -> Stack

Converts a 1.16.5 wire stack.

pub fn to_legacy(&self) -> ItemStack

The 1.8 wire form (count truncated to a byte like Java’s writeByte).

pub fn to_modern(&self) -> ItemStack

The 1.16.5 wire form.

pub fn same_item(&self, other: &Stack) -> bool

Same item, damage and NBT (vanilla’s item + damage check and its NBT check); counts are not compared.

pub fn nbt_eq(&self, other: &Stack) -> bool

Vanilla’s tag comparison: both absent, or both present and equal as trees.

pub fn equals_exact(&self, other: &Stack) -> bool

Exact equality as the server checks the clicked item (count, id, damage, NBT).

Trait Implementations

impl Clone for Stack

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Stack

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

Formats the value using the given formatter.

impl Eq for Stack

impl Hash for Stack

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Stack

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

Equality operator ==.

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

Inequality operator !=.
