Struct entity_data::Archetype

source · [−]

pub struct Archetype { /* private fields */ }

Expand description

A collection of entities with unique combination of components. An archetype can hold a maximum of 2^32-1 entities.

Implementations

source

pub fn get<C: Component>(&self, entity_id: u32) -> Option<&C>

Returns a reference to the component C of the specified entity id.

source

pub fn get_mut<C: Component>(&mut self, entity_id: u32) -> Option<&mut C>

Returns a mutable reference to the component C of the specified entity id.

source

pub fn len(&self) -> usize

Returns the number of entities in the archetype.
