About

This library allows you control the state of code execution using blink(1) LED notifier.

You simply wrap the code you want to track with transition library: ```rust use std::error::Error; use std::thread; use std::time::Duration; use transition::Transition;

fn main() -> Result<(), Box> { // start transition let notification = Transition::default().start()?;

// our example code
thread::sleep(Duration::from_secs(5));

// task finished with success
notification.notify_success()?;

Ok(())

} ```

What does it do?

1. After calling start(), blink(1) starts blinking with blue light. This is done in a separate thread.
2. Then our code is executing.
3. At the end we call notification.notify_success() (or notification.notify_failure()) which changes the color of LED to green (or red).

Supported colors: ```rust use transition::Led;

let color = Led::Blue; match color { Led::Red => println!("red"), Led::Green => println!("green"), Led::Blue => println!("blue"), Led::Yellow => println!("yellow"), Led::Orange => println!("orange"), Led::Pink => println!("pink"), Led::Cyan => println!("cyan"), Led::White => println!("white"), Led::Blank => println!("turn off the led"), }

```
