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: utils.rs
    path of file: ./repos/pilka/src
    
    the code of the file until where you have to start completion: use color_eyre::*;

use crate::{SCREENSHOTS_FOLDER, SHADER_DUMP_FOLDER, SHADER_PATH};
use pilka_types::{ImageDimentions, ShaderFlavor};

use std::{
    ffi::OsStr,
    fs::File,
    io::{self, BufWriter, Write},
    path::{Path, PathBuf},
    time::{Duration, Instant},
};

pub fn print_help() {
    pr
    
pub fn print_help() {
    println!("\n- `F1`:   Print help");
    println!("- `F2`:   Toggle play/pause");
    println!("- `F3`:   Pause and step back one frame");
    println!("- `F4`:   Pause and step forward one frame");
    println!("- `F5`:   Restart playback at frame 0 (`Time` and `Pos` = 0)");
    println!("- `F6`:   Print parameters");
    println!("- `F7`:   Toggle profiler");
    println!("- `F8`:   Switch backend");
    println!("- `F10`:  Save shaders");
    println!("- `F11`:  Take Screenshot");
    println!("- `F12`:  Start/Stop record video");
    println!("- `ESC`:  Exit the application");
    println!("- `Arrows`: Change `Pos`\n");
