Struct bevy_egui::render_systems::ExtractedEguiTextures

pub struct ExtractedEguiTextures<'w> {
    pub egui_textures: Res<'w, ExtractedEguiManagedTextures>,
    pub user_textures: Res<'w, EguiUserTextures>,
}

Extracted Egui textures.

Fields

egui_textures: Res<'w, ExtractedEguiManagedTextures>

Maps Egui managed texture ids to Bevy image handles.

user_textures: Res<'w, EguiUserTextures>

Maps Bevy managed texture handles to Egui user texture ids.

Implementations

impl ExtractedEguiTextures<'_>

pub fn handles( &self ) -> impl Iterator<Item = (EguiTextureId, AssetId<Image>)> + '_

Returns an iterator over all textures (both Egui and Bevy managed).

Trait Implementations

impl SystemParam for ExtractedEguiTextures<'_>

type State = FetchState

Used to store data which persists across invocations of a system.

type Item<'w, 's> = ExtractedEguiTextures<'w>

The item type returned when constructing this system param. The value of this associated type should be Self, instantiated with new lifetimes.

fn init_state(world: &mut World, system_meta: &mut SystemMeta) -> Self::State

Registers any World access used by this SystemParam and creates a new instance of this param’s State.

fn new_archetype( state: &mut Self::State, archetype: &Archetype, system_meta: &mut SystemMeta )

For the specified Archetype, registers the components accessed by this SystemParam (if applicable).

fn apply(state: &mut Self::State, system_meta: &SystemMeta, world: &mut World)

Applies any deferred mutations stored in this SystemParam’s state. This is used to apply Commands during apply_deferred.

unsafe fn get_param<'w, 's>( state: &'s mut Self::State, system_meta: &SystemMeta, world: UnsafeWorldCell<'w>, change_tick: Tick ) -> Self::Item<'w, 's>

Creates a parameter to be passed into a SystemParamFunction.
