Benchmarking

This crate can be used to execute something and measure the execution time in nano seconds. It does not output anything to the screen and the filesystem.

Examples

```rust extern crate benchmarking;

fn main() { const VEC_LENGTH: usize = 100;

benchmarking::warm_up();

let bench_result = benchmarking::measure_function(|measurer| {
    let mut vec: Vec<usize> = Vec::with_capacity(VEC_LENGTH);

    measurer.measure(|| {
        for i in 0..VEC_LENGTH {
            vec.push(i);
        }
    });

    /*
        // Start the measurement
        for i in 0..VEC_LENGTH {
            vec.push(i);
        }
        // End the measurement
    */
}).unwrap();

println!("Filling 0 to 99 into a vec takes {:?}!", bench_result.elapsed());

} ```

```rust extern crate benchmarking;

fn main() { const VEC_LENGTH: usize = 100;

benchmarking::warm_up();

let bench_result = benchmarking::measure_function(|measurer| {
    let mut vec: Vec<usize> = Vec::with_capacity(VEC_LENGTH);

    measurer.measure_for_loop(0..VEC_LENGTH, |_, loop_seq| {
        vec.push(loop_seq);
    });

    /*
        for i in 0...VEC_LENGTH {
            // Start the measurement
            vec.push(i);
            // End the measurement
        }
    */
}).unwrap();

println!("Pushing a number into a vec takes {:?}!", bench_result.elapsed());

} ```

```rust extern crate benchmarking;

fn main() { const VEC_LENGTH: usize = 100;

benchmarking::warm_up();

let bench_result = benchmarking::measure_function(|measurer| {
    let mut vec: Vec<usize> = Vec::with_capacity(VEC_LENGTH);

    measurer.measure_while_loop(|loop_seq| {
        loop_seq < VEC_LENGTH
    }, |loop_seq| {
        vec.push(loop_seq);
    });

    /*
        let mut i = 0;

        while i < VEC_LENGTH {
            // Start the measurement
            vec.push(i);
            // End the measurement

            i += 1;
        }
    */
}).unwrap();

println!("Pushing a number into a vec takes {:?}!", bench_result.elapsed());

} ```

• The warm_up and warm_up_with_duration functions of the benchmarking crate runs on one thread. To warm up all CPUs, you can use the warm_up_multi_thread and warm_up_multi_thread_with_duration functions instead.
• The measure_function and measure_function_with_times functions of the benchmarking crate can execute a closure for N times. To execute it repeatly for a while instead, you can use the bench_function and bench_function_with_duration functions.
• To execute a closure with multiple threads to measure the throughput, you can use the multi_thread_bench_function and multi_thread_bench_function_with_duration functions of the benchmarking crate.
