Trait bevy_render::render_graph::Node

pub trait Node: Downcast + Send + Sync + 'static {
    fn update(
        &mut self, 
        world: &World, 
        render_context: &mut dyn RenderContext, 
        input: &ResourceSlots,

    fn input(&self) -> &[ResourceSlotInfo] { ... }
    fn output(&self) -> &[ResourceSlotInfo] { ... }
    fn prepare(&mut self, _world: &mut World) { ... }

Required methods

fn update(
    &mut self,
    world: &World,
    render_context: &mut dyn RenderContext,
    input: &ResourceSlots,
    output: &mut ResourceSlots
)

Run the graph node logic. This runs once per graph run after Node::prepare has been called on all nodes.

Provided methods

fn input(&self) -> &[ResourceSlotInfo]

fn output(&self) -> &[ResourceSlotInfo]

fn prepare(&mut self, _world: &mut World)

Prepare the graph node with unique world access. This runs once per graph run before Node::update is called.

Implementations

impl dyn Node

pub fn is<__T: Node>(&self) -> bool

Returns true if the trait object wraps an object of type __T.

pub fn downcast<__T: Node>(self: Box<Self>) -> Result<Box<__T>, Box<Self>>

Returns a boxed object from a boxed trait object if the underlying object is of type __T. Returns the original boxed trait if it isn’t.

pub fn downcast_rc<__T: Node>(self: Rc<Self>) -> Result<Rc<__T>, Rc<Self>>

Returns an Rc-ed object from an Rc-ed trait object if the underlying object is of type __T. Returns the original Rc-ed trait if it isn’t.

pub fn downcast_ref<__T: Node>(&self) -> Option<&__T>

Returns a reference to the object within the trait object if it is of type __T, or None if it isn’t.

pub fn downcast_mut<__T: Node>(&mut self) -> Option<&mut __T>

Returns a mutable reference to the object within the trait object if it is of type __T, or None if it isn’t.
