where
T: HasSchema;
Expand description
Wrapper for the CompMut
SystemParam
used as QueryItem
to iterate
over entities optionally and mutably retrieving components from ComponentStore
.
Entities iterated over will not be filtered by OptionalQueryItemMut
.
See OptionalMut
helper func for constructing OptionalQueryItemMut
and usage
