#[repr(transparent)]
pub struct Entity(_);

Trait Implementations

impl Clone for Entity

fn clone(&self) -> Self

Returns a copy 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

Formats the value using the given formatter.

impl DefaultFilter for Entity

type Filter = EntityFilterTuple<Any, Passthrough>

The filter constructed.

impl Hash for Entity

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, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<Entity> for Entity

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

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

type Element = <Self::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() -> Self::Read

Returns the component types read by the view.

fn writes_types() -> Self::Write

Returns the component types written to by the view.

fn reads<D: Component>() -> bool

Returns true if the view reads the specified data type.

fn writes<D: Component>() -> bool

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>
) -> Self::Iter

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