Trait zengine_ecs::Component

pub trait Component: Any + Sync + Send + Debug { }

A data type that can be used to store data for an Entity

Component is a derivable trait: you could implement it by applying a #[derive(Component)] attribute to your data type. To correctly implement this trait your data must satisfy the Sync + Send + Debug trait bounds.

Implementing the trait for foreign types

As a consequence of the orphan rule, it is not possible to separate into two different crates the implementation of Component from the definition of a type. For this reason is not possible to implement the Component trat for a type defined in a third party library. The newtype pattern is a simple workaround to this limitation:

The following example gives a demonstration of this pattern.

use external_crate::TypeThatShouldBeAComponent;

#[derive(Component)]
struct MyWrapper(TypeThatShouldBeAComponent)
