.
§type Item = NodeQueryReadOnlyItem<'__w>
type Item = NodeQueryReadOnlyItem<'__w>
The item returned by this
WorldQuery
§type Fetch = NodeQueryReadOnlyFetch<'__w>
type Fetch = NodeQueryReadOnlyFetch<'__w>
Per archetype/table state used by this
WorldQuery
to fetch Self::Item
§type ReadOnly = NodeQueryReadOnly
type ReadOnly = NodeQueryReadOnly
The read-only variant of this
WorldQuery
, which satisfies the ReadOnlyWorldQuery
trait.§type State = NodeQueryState
type State = NodeQueryState
State used to construct a
Self::Fetch
. This will be cached inside QueryState
,
so it is best to move as much data / computation here as possible to reduce the cost of
constructing Self::Fetch
.§fn shrink<'__wlong, '__wshort>(
item: <NodeQueryReadOnly as WorldQuery>::Item<'__wlong>
) -> <NodeQueryReadOnly as WorldQuery>::Item<'__wshort>where
'__wlong: '__wshort,
fn shrink<'__wlong, '__wshort>( item: <NodeQueryReadOnly as WorldQuery>::Item<'__wlong> ) -> <NodeQueryReadOnly as WorldQuery>::Item<'__wshort>where '__wlong: '__wshort,
This function manually implements subtyping for the query items.

Creates a new instance of this fetch. Read more

unsafe fn clone_fetch<'__w>( _fetch: &<NodeQueryReadOnly as WorldQuery>::Fetch<'__w> ) -> <NodeQueryReadOnly as WorldQuery>::Fetch<'__w>
While this function can be called for any query, it is always safe to call if
Self: ReadOnlyWorldQuery
holds. Read more§const IS_DENSE: bool = true
const IS_DENSE: bool = true
Returns true if (and only if) every table of every archetype matched by this fetch contains
all of the matched components. This is used to select a more efficient “table iterator”
for “dense” queries. If this returns true,
WorldQuery::set_table
must be used before
WorldQuery::fetch
can be called for iterators. If this returns false,
WorldQuery::set_archetype
must be used before WorldQuery::fetch
can be called for
iterators.§const IS_ARCHETYPAL: bool = true
const IS_ARCHETYPAL: bool = true
Returns true if (and only if) this Fetch relies strictly on archetypes to limit which
components are accessed by the Query. Read more

Return the

exist.§impl<T> Downcast for Twhere
