I went through this code and it makes sense to me (other than the change to disable cargo test which should be removed prior to merging) -- thanks @nevi-me

FYI I merged #9653 / ARROW-11896 for the Rust CI checks which may affect this PR. If you see "Rust / AMD64 Debian 10 Rust stable test workspace" failing with a linker error or no logs, rebasing against master will hopefully fix the problem
