Headway is a progress bar library focused on ergonomics, just getting out of your way and letting you get back to writing all that other code.

# In Cargo.toml
headway = "0.1"

use headway::ProgressBarIterable;

for _ in (0..100).progress() {
    // Do important stuff here
}

Take a look at the documentation for more examples.

Compared to other progress bar libraries, headway:

• Allows multiple progress bars to run concurrently out of the box, even from separate threads.
• Integrates with stdout so that printing to stdout does not mess up either your progress bars or your printed text.
• Allows easily splitting progress bars into smaller parts (makes it easy to break up tasks over multiple threads, or into semantically separate parts).
• Takes advantage of unicode to increment the progress bar more smoothly.
• Works properly even if you only increment it very seldom (many libraries will show stale data if the bar is not incremented often enough).

Take a look at the documentation for more details.

If you are looking for a progress bar that can be styled in a variety of ways then other libraries may be better. Headway currently does not have any support for styling progress bars.
