Module `indicatif`

Progress bars and spinners for CLI applications.

indicatif provides progress bars, spinners, and other progress indicators for command-line applications. It handles terminal width, colors, and smooth updates.

The main types are ProgressBar for single progress indicators and MultiProgress for displaying multiple progress bars simultaneously. Use ProgressStyle to customize the appearance.

Examples

Simple progress bar:

use indicatif::ProgressBar;

let pb = ProgressBar::new(100);
for i in 0..100 {
    pb.inc(1);
    // Do work...
}
pb.finish_with_message("done");

Styled progress bar:

use indicatif::{ProgressBar, ProgressStyle};

let pb = ProgressBar::new(1000);
pb.set_style(ProgressStyle::with_template(
    "{spinner:.green} [{elapsed_precise}] [{bar:40.cyan/blue}] {pos}/{len} ({eta})"
).unwrap());

for _ in 0..1000 {
    pb.inc(1);
}
pb.finish();

Spinner for indeterminate progress:

use indicatif::ProgressBar;
use std::time::Duration;

let spinner = ProgressBar::new_spinner();
spinner.set_message("Loading...");
spinner.enable_steady_tick(Duration::from_millis(100));
// Do work...
spinner.finish_with_message("Done!");
