Crate timethis

A simple, single-dependency crate to benchmark the execution time of a block of code.

Examples

Time single execution

#[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);
}

Time multiple execution

#[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);
}

Macros

timethis

Runs the block of code once and returns the execution time in a std::time::Duration.

timethis_loops

Runs the block of code n times and returns the execution time in a std::time::Duration
