## monitor_rs
A convenience library that provides an easier way to use the combination of Mutex+Condvar in Rust. The concept is known as [Monitor synchronization construct](https://en.wikipedia.org/wiki/Monitor_%28synchronization%29) and is similar to Java's synchronized() statement.

### Usage
Put this in your `Cargo.toml`:

```toml
[dependencies]
monitor = "0.1.0"
```

And this in your crate root:
```rust
extern crate monitor;
```


### Example
```rust
extern crate monitor;

use std::time::Duration;
use std::sync::Arc;
use std::thread;
use monitor::Monitor;

fn main() {
    let mon = Arc::new(Monitor::new(false));
    {
        let mon = mon.clone();
        let _ = thread::spawn(move || {
            thread::sleep(Duration::from_millis(1000));
            
            mon.with_lock(|mut done| {     // done is a monitor::MonitorGuard<bool>
                *done = true;
                done.notify_one();
            });
        });
    }
    
    mon.with_lock(|mut done| {
        while !*done {
            done.wait();
        }
        println!("finished waiting");
    });
}
```
