Enum PatchOrigin 

pub enum PatchOrigin {
    Creation,
    Change,
    Unknown,
}

Whether a patch creates its entity, as far as its source says.

Every patch carries only the fields that changed. For a key a view holds that is all it needs; for one it does not hold, the patch is the entity only if it created it.

Variants

Creation

The source marked the patch as its entity’s creation (arete_interpreter::WholeEntity::Created), so it is all of the entity.

Change

The source marks every creation and did not mark this patch, so it changes an entity created earlier and is only part of it. A VM linked through crate::EntityResync is such a source.

Unknown

The source does not mark creations. A patch for a key the view does not hold is taken for a new entity unless the view remembers evicting it.
