§type Item<'__w> = EguiContextQueryReadOnlyItem<'__w>
type Item<'__w> = EguiContextQueryReadOnlyItem<'__w>
The item returned by this [
WorldQuery
]§type Fetch<'__w> = EguiContextQueryReadOnlyFetch<'__w>
type Fetch<'__w> = EguiContextQueryReadOnlyFetch<'__w>
Per archetype/table state used by this [
WorldQuery
] to fetch Self::Item
§type ReadOnly = EguiContextQueryReadOnly
type ReadOnly = EguiContextQueryReadOnly
The read-only variant of this [
WorldQuery
], which satisfies the [ReadOnlyWorldQuery
] trait.§type State = EguiContextQueryState
type State = EguiContextQueryState
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, '__wshort>( item: <EguiContextQueryReadOnly as WorldQuery>::Item<'__wlong> ) -> <EguiContextQueryReadOnly as WorldQuery>::Item<'__wshort>
This function manually implements subtyping for the query items.

While this function can be called for any query, it is always safe to call if
Self: ReadOnlyWorldQuery
holds. Read moresource§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.source§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
