Also test_reverse_scan_with_struct is not correct, I just add more assertions on it, you can check it on https://github.com/tonbo-io/tonbo/commit/af4a1d5b950002dfff0ec757dbb1eb478c2c9720, it shows that reverse iteration returns zero numbers of element, and rest of assertions are skipped. Because swap lower bound and upper bound does not make sense to crossbeam SkipMap, it does not support this to reverse the iteration in that way, you need to change the behavior of MutableScan to realize that.
