Trait Implementations§

Source§

impl QueryData for NodeQueryReadOnly

SAFETY: we assert fields are readonly below

Source§

unsafe fn fetch<'__w, '__s>( _state: &'__s <NodeQueryReadOnly as WorldQuery>::State, _fetch: &mut <NodeQueryReadOnly as WorldQuery>::Fetch<'__w>, _entity: Entity, _table_row: TableRow, ) -> <NodeQueryReadOnly as QueryData>::Item<'__w, '__s>

SAFETY: we call fetch for each member that implements Fetch.

Source§

const IS_READ_ONLY: bool = true

True if this query is read-only and may not perform mutable access.
Source§

type ReadOnly = NodeQueryReadOnly

The read-only variant of this QueryData, which satisfies the ReadOnlyQueryData trait.
Source§

type Item<'__w, '__s> = NodeQueryReadOnlyItem<'__w, '__s>

The item returned by this WorldQuery This will be the data retrieved by the query, and is visible to the end user when calling e.g. Query<Self>::get.
Source§

fn shrink<'__wlong, '__wshort, '__s>( item: <NodeQueryReadOnly as QueryData>::Item<'__wlong, '__s>, ) -> <NodeQueryReadOnly as QueryData>::Item<'__wshort, '__s>

This function manually implements subtyping for the query items.
Source§

fn provide_extra_access( state: &mut <NodeQueryReadOnly as WorldQuery>::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 more

Source§

fn release_state<'__w>( _item: <NodeQueryReadOnly as QueryData>::Item<'__w, '_>, ) -> <NodeQueryReadOnly as QueryData>::Item<'__w, 'static>
