Detailed Description

Runtime for dummy binding target.

Dummy binding target runtime is used when the binding has side effects that need to be executed, but writing to target value is not important. It is most commonly used with ToSourceBinding, that writes to a push source, but does not necessarily write a value in the target Node or RenderPass.

Dummy binding targets may also be used if the binding has other side effects that make writing the result value unnecessary, for example a CallbackBindingProcessor that executes user-defined code for the binding result value. Also ToSourceBinding is commonly used with DummyBindingTargetRuntime.

DummyBindingTargetRuntime is always considered to be connected.
