You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: mod.rs
    path of file: ./repos/UnicornConsole/unicorn/src/gfx
    
    the code of the file until where you have to start completion: pub mod fonts;
pub mod camera;
pub mod clip;
pub mod palette;
pub mod sprite;
pub mod framerate;

use log::{debug
    
    pub fn rect(&mut self, x0: i32, y0: i32, x1: i32, y1: i32, col: i32) {
        let x_min = cmp::min(x0, x1);
        let x_max = cmp::max(x0, x1);
        let y_min = cmp::min(y0, y1);
        let y_max = cmp::max(y0, y1);

        for x in x_min..(x_max + 1) {
            self.putpixel(x, y_min, col as u32, true);
            self.putpixel(x, y_max, col as u32, true);
        }
        for y in (y_min + 1)..y_max {
            self.putpixel(x0, y, col as u32, true);
            self.putpixel(x1, y, col as u32, true);
        }
    }
