pub struct Res<'w, T>where
T: Resource,{ /* private fields */ }
Expand description
Shared borrow of a Resource
.
See the Resource
documentation for usage.
If you need a unique mutable borrow, use ResMut
instead.
Panics
Panics when used as a SystemParameter
if the resource does not exist.
Use Option<Res<T>>
instead if the resource might not always exist.
