Struct plank_ecs::Entity

pub struct Entity(_, _);

An entity index. They are created using the Entities struct. They are used as indices with Components structs.

Entities are conceptual “things” which possess attributes (Components). As an exemple, a Car (Entity) has a Color (Component), a Position (Component) and a Speed (Component).

Implementations

impl Entity

pub fn index(&self) -> u32

Returns the index of this Entity.

In most cases, you do not want to use this directly. However, it can be useful to create caches to improve performances.

pub fn generation(&self) -> u32

Returns the generation of this Entity.

In most cases, you do not want to use this directly. However, it can be useful to create caches to improve performances.
