Expand description

A common trait for EntityBuilder and LazyBuilder, allowing either to be used. Entity is definitely alive, but the components may or may not exist before a call to World::maintain.

Required Methods

Appends a component and associates it with the entity.

If a component was already associated with the entity, it should overwrite the previous component.

Panics

Panics if the component hasn’t been register()ed in the World.

Finishes the building and returns the entity.

Provided Methods

Convenience method that calls self.with(component) if Some(component) is provided

Panics

Panics if the component hasn’t been register()ed in the World.
