# `scope_timer` usage
`scope_timer` crate provides very easy way to create a timer and trace the info.
## Examples
```rs
fn fib(n: u64) -> u64 {
if n <= 1 {
return 1;
}
fib(n - 1) + fib(n - 2)
}
fn main() {
let _handle = TimerScope::new("my_timer", TimeFormat::SecondsF32(3), None, false);
println!("{}", fib(46));
}
```
```
Output:
Label: my_timer | Time: 5.973
```
Also, you can do like this:
```rs
let mut handle = TimerScope::default();
handle.name = "my_timer";
handle.log_level = Some(LogLevel::Info);
```
## 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:
```rs
env_logger::init();
let mut handle = TimerScope::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.
Like this:
```rs
let _handle = TimerScope {
name: "my_timer",
..Default::default()
};
```
But PR are welcome. I will try to fix this issue to make timer omega-easy-to-use.
