The read-only variant of this

Fetch

for either the given entity
in the current Table
,
or for the given entity
in the current Archetype
. This must always be called after
WorldQuery::set_table
with a table_row
in the range of the current Table

WorldQuery::set_archetype
with an entity
in the current archetype.

fn provide_extra_access( _state: &mut Self::State, _access: &mut Access, _available_access: &Access, )
Offers additional access above what we requested in
update_component_access
.
Implementations may add additional access that is a subset of available_access
and does not conflict with anything in access
,
and must update access
to include that access. Read moreSource§impl ReleaseStateQueryData for EntityLocation
