Struct EguiContext

pub struct EguiContext { /* private fields */ }

A component for storing bevy_egui context.

Implementations

impl EguiContext

pub fn get_mut(&mut self) -> &mut Context

Borrows the underlying Egui context mutably.

Even though the mutable borrow isn’t necessary, as the context is wrapped into RwLock, using the immutable getter is gated with the immutable_ctx feature. Using the immutable borrow is discouraged as it may cause unpredictable blocking in UI systems.

When the context is queried with &mut EguiContext, the Bevy scheduler is able to make sure that the context isn’t accessed concurrently and can perform other useful work instead of busy-waiting.

Trait Implementations

impl Clone for EguiContext

fn clone(&self) -> EguiContext

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Component for EguiContext

where Self: Send + Sync + 'static,

Required Components: EguiContextSettings, EguiInput, EguiContextPointerPosition, EguiContextPointerTouchId, EguiContextImeState, EguiFullOutput, EguiRenderOutput, EguiOutput, RenderTargetSize, CursorIcon.

A component’s Required Components are inserted whenever it is inserted. Note that this will also insert the required components of the required components, recursively, in depth-first order.

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::Table

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have [Component<Mutability = Mutable>], while immutable components will instead have [Component<Mutability = Immutable>].

fn register_required_components( requiree: ComponentId, components: &mut ComponentsRegistrator<'_>, required_components: &mut RequiredComponents, inheritance_depth: u16, recursion_check_stack: &mut Vec<ComponentId>, )

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn register_component_hooks(hooks: &mut ComponentHooks)

👎Deprecated since 0.16.0: Use the individual hook methods instead (e.g., Component::on_add, etc.)

Called when registering this component, allowing mutable access to its ComponentHooks.

fn on_add() -> Option<for<'w> fn(_: DeferredWorld<'w>, _: HookContext)>

Gets the on_add ComponentHook for this Component if one is defined.

fn on_insert() -> Option<for<'w> fn(_: DeferredWorld<'w>, _: HookContext)>

Gets the on_insert ComponentHook for this Component if one is defined.

fn on_replace() -> Option<for<'w> fn(_: DeferredWorld<'w>, _: HookContext)>

Gets the on_replace ComponentHook for this Component if one is defined.

fn on_remove() -> Option<for<'w> fn(_: DeferredWorld<'w>, _: HookContext)>

Gets the on_remove ComponentHook for this Component if one is defined.

fn on_despawn() -> Option<for<'w> fn(_: DeferredWorld<'w>, _: HookContext)>

Gets the on_despawn ComponentHook for this Component if one is defined.

fn map_entities<E>(_this: &mut Self, _mapper: &mut E)

where E: EntityMapper,

Maps the entities on this component using the given EntityMapper. This is used to remap entities in contexts like scenes and entity cloning. When deriving Component, this is populated by annotating fields containing entities with #[entities]

impl Default for EguiContext

fn default() -> EguiContext

Returns the “default value” for a type.

impl ExtractComponent for EguiContext

where Self: Clone,

type QueryData = &'static EguiContext

ECS ReadOnlyQueryData to fetch the components to extract.

type QueryFilter = ()

Filters the entities with additional constraints.

type Out = EguiContext

The output from extraction.

fn extract_component(item: QueryItem<'_, Self::QueryData>) -> Option<Self::Out>

Defines how the component is transferred into the “render world”.
