Console progress bar for Rust Inspired from [pb](http://github.com/cheggaaa/pb), support and 

tested on MacOS, Linux and Windows

### Examples

1. simple example

```rust

use pbr::ProgressBar;

use std::thread;

fn main() {

    let count = 1000;

    let mut pb = ProgressBar::new(count);

    pb.format("╢▌▌░╟");

    for _ in 0..count {

        pb.inc();

        thread::sleep_ms(200);

    }

    pb.finish_print("done");

}

```

2. MultiBar example. see full example [here](https://github.com/a8m/pb/blob/master/examples/multi.rs)

```rust

use std::thread;

use pbr::MultiBar;

use std::time::Duration;

fn main() {

    let mut mb = MultiBar::new();

    let count = 100;

    mb.println("Application header:");

    let mut p1 = mb.create_bar(count);

    let _ = thread::spawn(move || {

        for _ in 0..count {

            p1.inc();

            thread::sleep(Duration::from_millis(100));

        }

        // notify the multibar that this bar finished.

        p1.finish();

    });

    mb.println("add a separator between the two bars");

    let mut p2 = mb.create_bar(count * 2);

    let _ = thread::spawn(move || {

        for _ in 0..count * 2 {

            p2.inc();

            thread::sleep(Duration::from_millis(100));

        }

        // notify the multibar that this bar finished.

        p2.finish();

    });

    // start listen to all bars changes.

    // this is a blocking operation, until all bars will finish.

    // to ignore blocking, you can run it in a different thread.

    mb.listen();

}

```

3. Broadcast writing (simple file copying)

```rust

#![feature(io)]

use std::io::copy;

use std::io::prelude::*;

use std::fs::File;

use pbr::{ProgressBar, Units};

fn main() {

    let mut file = File::open("/usr/share/dict/words").unwrap();

    let n_bytes = file.metadata().unwrap().len() as usize;

    let mut pb = ProgressBar::new(n_bytes);

    pb.set_units(Units::Bytes);

    let mut handle = File::create("copy-words").unwrap().broadcast(&mut pb);

    copy(&mut file, &mut handle).unwrap();

    pb.finish_print("done");

}

```
