Enum LoadOp 

pub enum LoadOp {
    Clear,
    Load,
}

What a render pass attachment does with the contents it already holds before the pass draws anything.

Replaces the "clear" / "load" string literals that GpuRenderPassColorAttachment.loadOp and GpuRenderPassDepthStencilAttachment.depthLoadOp accept. A typo in a string literal is a silent runtime failure (the browser rejects the pass and the frame renders nothing); a typo in a variant is a compile error.

Variants

Clear

Overwrite the attachment with its clear value before drawing.

The clear value is ColorAttachment::clear for color attachments and DepthStencilAttachment::depth_clear for depth-stencil attachments. WebGPU requires the clear value to be present whenever this variant is used, which is why the clear fields on those two structs are Option and paired with a non-optional load op rather than with Option<&'static str> defaults resolved by heuristic.

Load

Keep the attachment’s existing contents and draw over them.

The clear value must be absent; any value present is ignored.
