Struct Entity 

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

An entity index. They are created using the Entities struct. They are used as indices with Components structs.

Entities are conceptual “things” which possess attributes (Components). As an exemple, a Car (Entity) has a Color (Component), a Position (Component) and a Speed (Component).

Implementations

impl Entity

pub fn index(&self) -> u32

Returns the index of this Entity.

In most cases, you do not want to use this directly. However, it can be useful to create caches to improve performances.

pub fn generation(&self) -> u32

Returns the generation of this Entity.

In most cases, you do not want to use this directly. However, it can be useful to create caches to improve performances.

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 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.
