V-Regex Bug with the negation of slash (/)

[noxomix]

Describe the bug

This Bug occurs in the vlang regex module , with the following: [^/]+. (and pretty sure also with the * instead + ; not tested more)

Reproduction Steps

import regex

fn main() {
    re := regex.regex_opt(r'^/admin/[^/]+$') or { panic(0) }
    if re.matches_string('/admin/something') {
        //should match
        println('This is ok and should match!')
    }
    if re.matches_string('/admin/') {
        //should NOT match
        println('This should not be matched...')
    }
    if re.matches_string('/admin') {
        //should NOT match
        println('This is not matched tho...')
    }
}

Expected Behavior

Im expecting to match everything except slash (/)

So this should be matched:
/admin/something or this /admin/124

This should not (!) be matched:
/admin/, /admin, /admin/something/other

Current Behavior

/admin/ is getting matched but no character is provided behind the last slash so why is this matching (?)

Possible Solution

I have no idea but maybe it has something todo with the piviot ? Because it is used for negation + for marking the "start of a string".

Additional Information/Context

This is my regex: ^/admin/[^/]+$

But its also not working without the $ and without the first ^...

I tried with flags aswell, like this rg_bin or how its called again and so on.
