Borderline

Borderline is a Crate to render borders to the terminal. You can place text or progress bars inside the borders. The usage is as simple as:

use borderline::LineBuilder;

// Create a line builder:
let mut lb = LineBuilder::new();

// Print the header first:
borderline::print_header("Borderline Test-Drive");

// Now, we are able to attach as many "line" as we want.
// Every line must be started with a call to `line_begin`
// and ended with a call to `line_end`:
lb.line_begin("- Loading...");

// perform other actions here...

// When ending a line, you can specify the second part
// of the line, which will be printed on the right side:
lb.line_end("done.");

// You can also print a progress bar:
lb.line_begin("- Loading many files:");

// Set up the progress bar using the total number of steps:
lb.progress_bar_setup(1_000);

// Do some work and update the progress bar:
for i in 0..1_000 {
    sleep(std::time::Duration::from_millis(50));
    lb.progress_bar_update(i);
}

// End the progress bar:
lb.progressbar_end();

// End the line and print the second text part:
lb.line_end("done.");

// At the end, we can print the closing border:
borderline::print_border();

While the progress bar is active:

When the program is done:

In case that the given text is too long, it gets wrapped at word boundaries. When this is not possible, the text is wrapped at the given width.
