[Feedback]: Idiomatic rust

[Uzaaft]

Just some general feedback on your code:

1. For your struct Place(line 9-13), you seem to implement a default implemention for your struct with arbritary values. This can be reduced to:

#[derive(Default)]
struct Place {
    x: i32,
    y: i32,
    z: i32
}

Which will implement default values for your struct(most likely just 0's).

2. From line 83-89
   You can use iter().map() instead, which is moe in line with idiomatic rust.

The usage of self: &Self is not idiomatic, and can be rewritten to:
&self
