Struct ItemEnchantments 

pub struct ItemEnchantments {
    pub levels: FxHashMap<Identifier, u32>,
}

Enchantments stored on an item. Maps enchantment key to level.

Used by both the minecraft:enchantments component (on enchanted items) and the minecraft:stored_enchantments component (on enchanted books).

Vanilla moved tooltip visibility to the separate TOOLTIP_DISPLAY component.

Fields

levels: FxHashMap<Identifier, u32>

Implementations

impl ItemEnchantments

pub fn empty() -> Self

pub fn get_level(&self, enchantment: &Identifier) -> u32

pub fn set(&mut self, enchantment: Identifier, level: u32)

pub fn upgrade(&mut self, enchantment: Identifier, level: u32)

Vanilla Mutable.upgrade: keeps the higher of existing vs new level.

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn iter(&self) -> impl Iterator<Item = (&Identifier, &u32)>

Trait Implementations

impl Clone for ItemEnchantments

fn clone(&self) -> ItemEnchantments

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for ItemEnchantments

fn into_data(self) -> ComponentData

Converts this component value into ComponentData.

fn from_data(data: ComponentData) -> Option<Self>

Attempts to extract this component type from ComponentData. Returns None if the data is a different variant.

fn from_data_ref(data: &ComponentData) -> Option<&Self>

Attempts to get a reference to this component type from ComponentData. Returns None if the data is a different variant or if the type cannot be referenced directly (e.g., needs conversion).

impl Debug for ItemEnchantments

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

Formats the value using the given formatter.

impl Default for ItemEnchantments

fn default() -> Self

Returns the “default value” for a type.

impl FromNbtTag for ItemEnchantments

fn from_nbt_tag(tag: NbtTag<'_, '_>) -> Option<Self>

fn from_optional_nbt_tag( tag: Option<NbtTag<'_, '_>>, ) -> Result<Option<Self>, DeserializeError>

impl HashComponent for ItemEnchantments

fn hash_component(&self, hasher: &mut ComponentHasher)

Hashes this value into the given hasher.

fn compute_hash(&self) -> i32

Computes the hash of this value.

impl PartialEq for ItemEnchantments

fn eq(&self, other: &ItemEnchantments) -> 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.

impl ReadFrom for ItemEnchantments

fn read(data: &mut Cursor<&[u8]>) -> Result<Self>

Reads data from a cursor.

impl StructuralPartialEq for ItemEnchantments

impl ToNbtTag for ItemEnchantments

NBT format: compound with enchantment identifiers as keys and int levels as values.

fn to_nbt_tag(self) -> NbtTag

fn to_optional_nbt_tag(self) -> Option<NbtTag>

impl WriteTo for ItemEnchantments

Network format: VarInt count, then (VarInt enchantment_id, VarInt level) pairs.

fn write(&self, writer: &mut impl Write) -> Result<()>

Writes data to a writer.
