rustybar

rustybar is a small, dependency-light progress bar library for Rust that renders clean, modern-looking progress bars in the terminal.

It focuses on three things:

zero setup
fully customizable appearance
smooth real-time feedback for CLI tools

If you are writing downloaders, installers — this is made for that.

Installation

Add it to your project with:

cargo add rustybar

Quick Example

use rustybar::ProgressBar;
use std::{thread, time::Duration};

fn main() {
    let total = 20_000;
    let mut bar = ProgressBar::new("Downloading", 40, total);

    let mut done = 0;
    while done < total {
        done += 500;
        bar.tick(done);
        thread::sleep(Duration::from_millis(80));
    }
}

Run:

cargo run

Run Demo:

cargo run --example demo
