Struct bevy::ecs::archetype::ArchetypeId

pub struct ArchetypeId(_);

An opaque unique ID for a single Archetype within a World.

Archetype IDs are only valid for a given World, and are not globally unique. Attempting to use an archetype ID on a world that it wasn’t sourced from will not return the archetype with the same components. The only exception to this is EMPTY which is guaranteed to be identical for all Worlds.

Implementations

impl ArchetypeId

pub const EMPTY: ArchetypeId = ArchetypeId(0)

The ID for the Archetype without any components.

pub const INVALID: ArchetypeId = ArchetypeId(u32::MAX)

Safety:

This must always have an all-1s bit pattern to ensure soundness in fast entity id space allocation.

Trait Implementations

impl Clone for ArchetypeId

fn clone(&self) -> ArchetypeId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ArchetypeId

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

Formats the value using the given formatter.

impl Hash for ArchetypeId

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 Index<ArchetypeId> for Archetypes

type Output = Archetype

The returned type after indexing.

fn index( &self, index: ArchetypeId ) -> &<Archetypes as Index<ArchetypeId>>::Output

Performs the indexing (container[index]) operation.

impl IndexMut<ArchetypeId> for Archetypes

fn index_mut( &mut self, index: ArchetypeId ) -> &mut <Archetypes as Index<ArchetypeId>>::Output

Performs the mutable indexing (container[index]) operation.

impl PartialEq<ArchetypeId> for ArchetypeId

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
