				<div class="class-description"><p><code>AtomicFunctionNode</code> represents any function that can operate on atomic variable types
within a shader. In an atomic function, any modification to an atomic variable will
occur as an indivisible step with a defined order relative to other modifications.
Accordingly, even if multiple atomic functions are modifying an atomic variable at once
atomic operations will not interfere with each other.</p>
<p>This node can only be used with a WebGPU backend.</p></div>
