}

Initializer enum for RelationshipAccessor that allows to configure relationship for dynamic components.

Variants

Relationship

Describes a Relationship component.

Fields

entity_field_offset: usize

Offset of the field containing Entity from the base of the component.

Dynamic equivalent of Relationship::get.

linked_spawn: bool

Value of RelationshipTarget::LINKED_SPAWN for the Relationship::RelationshipTarget of this Relationship.

allow_self_referential: bool

Value of Relationship::ALLOW_SELF_REFERENTIAL of this Relationship.

relationship_target_getter: Arc<dyn Fn(&Components) -> Option<ComponentId>>

Getter for ComponentId of the RelationshipTarget counterpart. Should return None if RelationshipTarget isn’t registered yet.

RelationshipTarget

Describes a RelationshipTarget component.

Fields

iter: for<'a> unsafe fn(Ptr<'a>) -> Box<dyn Iterator<Item = Entity> + 'a>

Function that returns an iterator over all Entitys of this RelationshipTarget’s collection.

Dynamic equivalent of RelationshipTarget::iter.

Safety

Passed pointer must point to the value of the same component as the one that this accessor was registered to.

linked_spawn: bool

Value of RelationshipTarget::LINKED_SPAWN of this RelationshipTarget.

allow_self_referential: bool

Value of Relationship::ALLOW_SELF_REFERENTIAL for the Relationship of this RelationshipTarget.

relationship_getter: Arc<dyn Fn(&Components) -> Option<ComponentId>>

Getter for ComponentId of the Relationship counterpart. Should return None if Relationship isn’t registered yet.
