Trait RenderNode 

pub trait RenderNode: RenderNodeCpu {
    // Required method
    fn process(
        &self,
        inputs: &[&Texture],
        outputs: &[&Texture],
        ctx: &RenderContext,
    );

    // Provided methods
    fn input_count(&self) -> usize { ... }
    fn pass_count(&self) -> usize { ... }
}

GPU render node. Extends RenderNodeCpu so both paths are available.

Each node is responsible for creating and caching its own wgpu pipeline on first use. The pipeline is stored in a std::sync::OnceLock field so it is created exactly once per node instance.

process may submit one or more wgpu::CommandEncoder buffers. The RenderGraph guarantees that the queue processes them in submission order.

Required Methods

fn process( &self, inputs: &[&Texture], outputs: &[&Texture], ctx: &RenderContext, )

Run the GPU render pass.

inputs[i] are the source textures (len == input_count()). outputs[i] are pre-allocated Rgba8Unorm target textures (len == pass_count()). Write the final result into outputs[pass_count()-1].

Provided Methods

fn input_count(&self) -> usize

Number of input textures required by this node (default: 1).

fn pass_count(&self) -> usize

Number of render passes (default: 1). Multi-pass nodes (e.g. gaussian blur) return 2 or more.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
