Struct bevy_render::render_phase::DrawFunctionsInternal

pub struct DrawFunctionsInternal<P: PhaseItem> {
    pub draw_functions: Vec<Box<dyn Draw<P>>>,
    pub indices: TypeIdMap<DrawFunctionId>,
}

Stores all Draw functions for the PhaseItem type.

For retrieval, the Draw functions are mapped to their respective TypeIds.

Fields

draw_functions: Vec<Box<dyn Draw<P>>>

indices: TypeIdMap<DrawFunctionId>

Implementations

impl<P: PhaseItem> DrawFunctionsInternal<P>

pub fn prepare(&mut self, world: &World)

Prepares all draw function. This is called once and only once before the phase begins.

pub fn add<T: Draw<P>>(&mut self, draw_function: T) -> DrawFunctionId

Adds the Draw function and maps it to its own type.

pub fn add_with<T: 'static, D: Draw<P>>( &mut self, draw_function: D ) -> DrawFunctionId

Adds the Draw function and maps it to the type T

pub fn get_mut(&mut self, id: DrawFunctionId) -> Option<&mut dyn Draw<P>>

Retrieves the Draw function corresponding to the id mutably.

pub fn get_id<T: 'static>(&self) -> Option<DrawFunctionId>

Retrieves the id of the Draw function corresponding to their associated type T.

pub fn id<T: 'static>(&self) -> DrawFunctionId

Retrieves the id of the Draw function corresponding to their associated type T.

Fallible wrapper for Self::get_id()

Panics

If the id doesn’t exist, this function will panic.
