Struct DataComponentPatch

pub struct DataComponentPatch {
    pub components: IndexMap<DataComponentKind, Option<Box<dyn EncodableDataComponent>>>,
}

An update to an item’s data components.

Note that in vanilla items come with their own set of default components, and Azalea does not implement that yet.

Fields

components: IndexMap<DataComponentKind, Option<Box<dyn EncodableDataComponent>>>

Implementations

impl DataComponentPatch

pub fn get<T>(&self) -> Option<&T>

where T: DataComponent,

Returns the value of the component in the generic argument for this item.

let item_nutrition = item.components.get::<components::Food>()?.nutrition;

pub fn get_kind( &self, kind: DataComponentKind, ) -> Option<&(dyn EncodableDataComponent + 'static)>

pub fn has<T>(&self) -> bool

where T: DataComponent,

Returns whether the component in the generic argument is present for this item.

let is_edible = item.components.has::<components::Food>();

pub fn has_kind(&self, kind: DataComponentKind) -> bool

Trait Implementations

impl AzaleaRead for DataComponentPatch

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

impl AzaleaWrite for DataComponentPatch

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

impl Clone for DataComponentPatch

fn clone(&self) -> DataComponentPatch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataComponentPatch

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

Formats the value using the given formatter.

impl Default for DataComponentPatch

fn default() -> DataComponentPatch

Returns the “default value” for a type.

impl PartialEq for DataComponentPatch

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