Log Update

Log by overwriting the previous output in the terminal.

Useful for rendering progress bars, animations, etc.

Usage

This example will count down from 3 and then display Lift off! 🚀.

```rust extern crate log_update;

use log_update::LogUpdate;

use std::io::stdout; use std::thread::sleep; use std::time::Duration;

fn main() { // Construct the log updater let mut log_update = LogUpdate::new(stdout()).unwrap();

for i in [3, 2, 1].iter() {
    // Update log to show message
    log_update.render(&format!("Lift off in {}...", i)).unwrap();

    // Sleep for one second
    sleep(Duration::from_secs(1));
}

// Print final message
log_update.render("Lift off! 🚀").unwrap();

} ```
