pub fn recognize(op: &Op) -> Option<SetOp>Expand description
Recognize a VM ISA op as a set operation, if it is one. IntersectOp/UnionOp are the VM’s
first-class set ops; difference / symmetric_difference / complement have no VM ISA op yet (the AOT
tier emits them as IndexSet methods), so they are not recognized from a VM program — but their
kernels below are proven and ready to dispatch once those ops become first-class.
