Encapsulates egui::RawInput.

render_output: &'static mut EguiRenderOutput

Egui shapes and textures delta.

Trait Implementations

impl WorldQuery for EguiContextQuery

unsafe fn set_archetype<'__w>( _fetch: &mut <Self as WorldQuery>::Fetch<'__w>, _state: &Self::State, _archetype: &'__w Archetype, _table: &'__w Table )

SAFETY: we call set_archetype for each member that implements Fetch

unsafe fn set_table<'__w>( _fetch: &mut <Self as WorldQuery>::Fetch<'__w>, _state: &Self::State, _table: &'__w Table )

SAFETY: we call set_table for each member that implements Fetch

unsafe fn fetch<'__w>( _fetch: &mut <Self as WorldQuery>::Fetch<'__w>, _entity: Entity, _table_row: TableRow ) -> <Self as WorldQuery>::Item<'__w>

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

type Item<'__w> = EguiContextQueryItem<'__w>

The item returned by this [WorldQuery]

type Fetch<'__w> = EguiContextQueryFetch<'__w>

Per archetype/table state used by this [WorldQuery] to fetch Self::Item

type ReadOnly = EguiContextQueryReadOnly

The read-only variant of this [WorldQuery], which satisfies the [ReadOnlyWorldQuery] trait.

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: <EguiContextQuery as WorldQuery>::Item<'__wlong> ) -> <EguiContextQuery as WorldQuery>::Item<'__wshort>

This function manually implements subtyping for the query items.

unsafe fn init_fetch<'__w>( _world: &'__w World, state: &Self::State, _last_change_tick: u32, _change_tick: u32 ) -> <Self as WorldQuery>::Fetch<'__w>

Creates a new instance of this fetch.

unsafe fn clone_fetch<'__w>( _fetch: &<Self as WorldQuery>::Fetch<'__w> ) -> <Self as WorldQuery>::Fetch<'__w>

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

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

Returns true if (and only if) this Fetch relies strictly on archetypes to limit which components are accessed by the Query.

unsafe fn filter_fetch<'__w>( _fetch: &mut <Self as WorldQuery>::Fetch<'__w>, _entity: Entity, _table_row: TableRow ) -> bool

Safety

fn update_component_access( state: &Self::State, _access: &mut FilteredAccess<ComponentId> )

fn update_archetype_component_access( state: &Self::State, _archetype: &Archetype, _access: &mut Access<ArchetypeComponentId> )

fn init_state(world: &mut World) -> EguiContextQueryState

fn matches_component_set( state: &Self::State, _set_contains_id: &impl Fn(ComponentId) -> bool ) -> bool
