Possibly uninit binding, how do i make a net against this

help
1 
if ncnd.location == Position::new(0,0) {
      self.wander();

      return
}

used to get the error, however how do i create a safety net to enter the if scope if uninit?
pretty much does ncnd have a value? -> no: wander

Without more context, it's hard to tell what you want.

If ncnd.location would be an Option<T> you could check for it to be None instead of for it being a magic default value.

3 
let mut ncnd: &mut Plant;

for candidate in cinr {
    let ccd: f32 = distance_eucl(&self.location, &candidate.location);
    if ccd < shortest {
        shortest = ccd;
        ncnd = candidate;
    }
}

so i should make ncnd an option?
if so, thank you i didnt think of that
