impl QueryData for EntityLocation
SAFETY: Self
is the same as Self::ReadOnly
§type ReadOnly = EntityLocation
type ReadOnly = EntityLocation
The read-only variant of this
QueryData
, which satisfies the ReadOnlyQueryData
trait.source§impl WorldQuery for EntityLocation
impl WorldQuery for EntityLocation
SAFETY:
update_component_access
and update_archetype_component_access
do nothing.
This is sound because fetch
does not access components.
§type Item<'w> = EntityLocation
type Item<'w> = EntityLocation
The item returned by this
WorldQuery
For QueryData
this will be the item returned by the query.
For QueryFilter
this will be either ()
, or a bool
indicating whether the entity should be included
or a tuple of such things.§type Fetch<'w> = &'w Entities
type Fetch<'w> = &'w Entities
Per archetype/table state used by this
WorldQuery
to fetch Self::Item
§type State = ()
type State = ()
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: Self::Item<'wlong> ) -> Self::Item<'wshort>

source§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§unsafe fn set_archetype<'w>(
