pub trait ReleaseStateQueryData: QueryData {
// Required method
fn release_state<'w>(item: Self::Item<'w, '_>) -> Self::Item<'w, 'static>;
}Expand description
A QueryData that does not borrow from its QueryState.
This is implemented by most QueryData types.
The main exceptions are FilteredEntityRef, FilteredEntityMut, EntityRefExcept, and EntityMutExcept,
which borrow an access list from their query state.
Consider using a full EntityRef or EntityMut if you would need those.
Required Methods§
Sourcefn release_state<'w>(item: Self::Item<'w, '_>) -> Self::Item<'w, 'static>
fn release_state<'w>(item: Self::Item<'w, '_>) -> Self::Item<'w, 'static>
Releases the borrow from the query state by converting an item to have a 'static state lifetime.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
