Struct Entity

pub struct Entity { /* private fields */ }

A generational entity identifier used by the ECS.

Fields

• id: The slot index assigned by the allocator identifying this entity.
• generation: Monotonically increasing number preventing stale entity reuse.

Safety

• Two entities are considered identical only if both id and generation match.
• When an entity is destroyed, its generation is incremented. Holding an old Entity value after destruction is safe: APIs validate the generation and will treat it as dead, preventing accidental access to a recycled id.

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

Formats the value using the given formatter.

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, 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.
