一个简单的单依赖项库，用于测试代码块执行时间。

示例

计时单次执行

#[macro_use]
extern crate timethis;

fn main() {
    let time_taken = timethis!({
        let mut x = Vec::new();
        for i in 0..1000 {
            x.push(i);
        }
    });

    println!("Time taken for 1,000 pushes: {:?}", time_taken);
}

计时多次执行

#[macro_use]
extern crate timethis;

fn main() {
    let time_taken = timethis_loops!(10, {
        let mut x = Vec::new();
        for i in 0..1000 {
            x.push(i);
        }
    });

    println!("Time taken for 10,000 pushes: {:?}", time_taken);
}
