Yeah. Lot of people also use Ai generated code... so...

I have tested if clippy would warn me with a simple example (generates 6.7gb memory usage, be careful not to crash your computer if you add another 0...), while I watch with a system monitor (in KDE):

use std::thread;
use std::time;

fn main() {
    let mut vec = Vec::new(); // Create an empty Vector.

    for number in 0..900000000 {
        let bign: i64 = number * number;
        vec.push(bign);
    }

    thread::sleep(time::Duration::from_secs(10));
}

I used the pedantic option of clippy and the only thing it complained was about the notation of the number...:

$ cargo clippy -- -W clippy::pedantic
warning: long literal lacking separators

Surely that's not a memory leak, that's just the program using a lot of memory intentionally
