scope_timer usage

scope_timer crate provides very easy way to create a timer and trace the info.

Examples

    fn fib(n: u64) -> u64 {
        if n <= 1 {
            return 1;
        }
        
        fib(n - 1) + fib(n - 2)
    }
    
    fn main() {
        let _handle = ScopeTimer::new("my_timer", TimeFormat::SecondsF32(3), None, false);
        println!("{}", fib(46));
    }

Output:
Label: my_timer | Time: 5.973secs

Also, you can do like this:

    let mut handle = ScopeTimer::default();
    handle.name = "my_timer";
    handle.log_level = Some(LogLevel::Info);

or like this:

    let mut handle = scope_timer::ScopeTimer {
        label: "timer",
        time_format: TimeFormat::SecondsF32(3),
        now: std::time::Instant::now(),
        log_level: None,
        debug_only: true,
    };

    handle.label = "what"

Log Level

scope_timer crate has minimal dependencies. You can use log crate for your projects.

For this, you specify log level and use log logging implementation as example env_logger crate:

    env_logger::init();

    let mut handle = ScopeTimer::default();
    handle.name = "my_timer";
    handle.log_level = Some(LogLevel::Info);

Known Issues

You can't do more elegant timer creation that would be correct in work because occurs move which automatically occurs drop and you get double print of your timer (in time move and after move).

Like this:

    let _handle = ScopeTimer {
        name: "my_timer",
        ..Default::default()
    };

But PR are welcome. I will try to fix this issue to make timer omega-easy-to-use.
