"list_units" not working correctely

[hubblexplorer]

So i was trying to get a list of all units as in the doc's, but it doesn't work because returns a empty vector
fn test_status() { let units = systemctl::list_units(None, None); // all units let is_ok = units.is_ok(); println!("{}", is_ok); let new_units = units.unwrap(); println!("{}", new_units.len()); }
output
true 0
Test in the terminal
systemctl list-units | wc -l 199
I'm i doing something wrong or is something broken

after some digging I found out that "list_units" isn't the only one that isn't working correctly, the function responsible to pack everything has a lot of issues, some of the examples i found are :

• session-2.scope it fails because of the number in the name and

• systemd-fsck-root.service this one i don't understand why but I'm going to leave this here

○ systemd-fsck-root.service - File System Check on Root Device
     Loaded: loaded (/usr/lib/systemd/system/systemd-fsck-root.service; enabled-runtime; preset: disabled)
     Active: inactive (dead)
  Condition: start condition failed at Sat 2023-02-25 17:29:32 WET; 57min ago
             └─ ConditionPathIsReadWrite=!/ was not met
       Docs: man:systemd-fsck-root.service(8) ``` 

Also i will make a commit trying to fix the initial problem

inital commit for fix #11

Part of the problem is solved for example systemd-fsck-root.service is solved (link to commit) but all units with numbers will result in errors, if someone can find a fix for this problem it would be appreciated

@hubblexplorer the newest commit on main should fix this. Can you please recheck? Here https://github.com/gwbres/systemctl/actions/runs/5589518960/jobs/10217918506#step:8:1832 at least is a unit with a number.
