    ) -> Result<Option<T>, NoSuchEntity>;
}

Type that can be registered. Can be used to set components in ECS Worlds generated by genesis.

Required methods

fn register(
    &mut self,
    entity: Entity,
    item: T
) -> Result<Option<T>, NoSuchEntity>

Register the given item for the given entity. Returns Err(NoSuchEntity) if the given entity doesn’t exist. Otherwise, returns the previously associated item. For normal components used to generate a World, this is equivalent to calling .set() on the corresponding storage field.
