Struct DataComponentPatch 

pub struct DataComponentPatch { /* private fields */ }

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.

Implementations

impl DataComponentPatch

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

where T: DataComponentTrait,

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

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

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

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

where T: DataComponentTrait,

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

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

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

pub fn iter<'a>( &'a self, ) -> impl Iterator<Item = (DataComponentKind, Option<&'a (dyn EncodableDataComponent + 'static)>)> + 'a

pub unsafe fn unchecked_insert_component( &mut self, kind: DataComponentKind, value: Option<DataComponentUnion>, )

Insert a new component into this patch, or mark a component as removed.

Safety

The DataComponentUnion must be of the correct kind.

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 Drop for DataComponentPatch

fn drop(&mut self)

Executes the destructor for this 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.

impl Serialize for DataComponentPatch

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
