Struct Entity

pub struct Entity(/* private fields */);

An opaque identifier for an entity.

Trait Implementations

impl Clone for Entity

fn clone(&self) -> Entity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Entity

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

Formats the value using the given formatter.

impl DefaultFilter for Entity

type Filter = EntityFilterTuple<Any, Passthrough>

The filter constructed.

impl<'de> Deserialize<'de> for Entity

fn deserialize<D>( deserializer: D, ) -> Result<Entity, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Entity

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

where __H: Hasher,

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 Entity

fn eq(&self, other: &Entity) -> 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 Entity

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.

impl<'data> View<'data> for Entity

type Element = <<Entity as View<'data>>::Fetch as IntoIndexableIter>::Item

The type of component references returned.

type Fetch = EntityFetch<'data>

The fetch type yielded for each archetype.

type Iter = Iter<'data>

The iterator type which pulls entity data out of a world.

type Read = [ComponentTypeId; 0]

Contains the type IDs read by the view.

type Write = [ComponentTypeId; 0]

Contains the type IDs written by the view.

fn validate()

Determines if this view type is valid. Panics if checks fail.

fn validate_access(_: &ComponentAccess<'_>) -> bool

Returns true if the given component access includes all permissions required by the view.

fn reads_types() -> <Entity as View<'data>>::Read

Returns the component types read by the view.

fn writes_types() -> <Entity as View<'data>>::Write

Returns the component types written to by the view.

fn reads<D>() -> bool

where D: Component,

Returns true if the view reads the specified data type.

fn writes<D>() -> bool

where D: Component,

Returns true if the view writes to the specified data type.

fn requires_permissions() -> Permissions<ComponentTypeId>

Returns a permissions struct declaring the component accesses required by the view.

unsafe fn fetch( _: &'data Components, archetypes: &'data [Archetype], query: QueryResult<'data>, ) -> <Entity as View<'data>>::Iter

Creates an iterator which will yield slices of entity data for each archetype.

impl Copy for Entity
