Struct Entity 

pub struct Entity { /* private fields */ }

Unique entity identifier with generation tracking

Each entity has:

• id: Numeric identifier (can be reused after destruction)
• generation: Counter that increases when ID is reused

This prevents stale references: if you hold an old Entity handle, operations will fail safely because the generation won’t match.

Example

let entity = world.spawn()
    .insert(Position { x: 0.0, y: 0.0 })
    .id();

println!("{}", entity); // "Entity(0v0)"

Implementations

impl Entity

pub fn id(&self) -> u32

Returns the entity ID

pub fn generation(&self) -> u32

Returns the generation counter

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 Display 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.
