pub fn expand_anytime_steps(plan: &mut CuExecutionLoop) -> CuResult<()>Expand description
Expands every foreground anytime node of an already-computed plan into its chunked steps.
The node’s single Whole step becomes an CuStepPhase::AnytimeBase step
at its topological position, and max_refines CuStepPhase::AnytimeRefine
steps (one refine() quantum each) are woven between it and the earliest
step consuming the node’s output: one immediately after the base step, one
after each subsequent independent step, and the remainder contiguously
before the consumer. If max_refines is smaller than the gap, later gap
steps get no quantum between them; if the node has no consumer in this
plan, every refine step sits right after the base step.
The refine count must be known here — the emission count is the iteration
bound — which is why max_refines is mandatory for foreground anytime
nodes. How many quanta run and where they sit between other steps is
entirely this compile-time scheduling decision; the generated code carries
no counter.
