Struct RenderGraph 

pub struct RenderGraph {
    pub root: LayerNode,
    pub update: u64,
}

The scene as a tree of layers that a renderer draws.

Fields

root: LayerNode

The top layer; every other node of the graph is beneath it.

update: u64

How many scene updates the graph took: the number of the latest.

Implementations

impl RenderGraph

pub fn new(root: LayerNode) -> Self

Creates a graph around root at update zero.

pub fn node_count(&self) -> usize

Number of nodes in the graph. A layer counts once and each primitive of a draw run counts on its own.

pub fn heap_bytes(&self) -> usize

Estimated heap memory held beneath the root layer, in bytes, for memory reports.

pub fn collect_retained_visual_observation_nodes( &self, nodes: &mut HashSet<NodeId>, )

Replaces the set with the graph’s visual observation owners, retaining its capacity.

Trait Implementations

impl Clone for RenderGraph

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
