These three sit in luxfi/node under utils/, and P-Chain and X-Chain reach for them. Both chains have to leave that repository before it can be archived, and a chain should not have to depend on a node to measure a quantity in nLUX, keep a heap, or walk a sequence. units imports nothing at all; heap wanted only Zero, which is already here; iterator wanted heap and Zero. Three of iterator's tests exercise it against platformvm's state iterators. They stay with the node, and travel with platformvm, because a generic sequence should not be tested through one virtual machine's idea of state. What remains here covers the package on its own terms. Co-authored-by: Hanzo Dev <[email protected]>
