The constant needs to be set manually and is very easily out of sync (as currently is), potentially making random tests to fail. Instead we can use
*Flags::ALL_FLAGS.len()because*Flagshas to always be in sync with the enum as it wouldn't compile otherwise.Alternative would be https://doc.rust-lang.org/std/mem/fn.variant_count.html but it's unstable.
