Struct ComponentStore 

pub struct ComponentStore<T> { /* private fields */ }

Sparse component storage keyed by Entity. Indexed directly by the entity’s index, with the stored generation checked on every access so a stale Entity (held past a despawn) never reads or writes whatever new component ends up in the recycled slot.

Implementations

impl<T> ComponentStore<T>

pub fn new() -> Self
