pub fn node_exec(
device: &Device,
c: &Circuit,
n: &Node,
no_fp4_kernel: bool,
) -> Option<Exec>Expand description
2026-10-01: How node n of c runs on device (weight-reading nodes only): its declared
formats on the device’s instructions (exec_of), or fp4_fallback when the class
compiles no FP4 block-scale kernel for it (no_fp4_kernel).
