arc_vec

• Arc Vector
  • Experimental work to run vectors in parallel

// Consider Arc<[T]> over Vec <T>
// Arc<[T]>
use arc_vec::alloc::arc_vec::ArcVec;
let my_num_arcvec_init: ArcVec<i32> = ArcVec::new();

example

• arcnew

use arc_vec::alloc::arc_vec::ArcVec;

fn main() {
    let my_arc_vec = ArcVec::new();
    my_arc_vec.push(10);
    println!("arc_vec int push : {}", my_arc_vec);
}

• macro

use arc_vec::arc_vec;

fn main() {
    let arc_test = arc_vec!(2);
    println!("arc_vec : {}", arc_test);
}

성능 평가 benches

• criterion.rs - Statistics-driven benchmarking library for Rust

cargo bench

• Understanding this report:

  • The plot on the left displays the average time per iteration for this benchmark. The shaded region shows the estimated probability of an iteration taking a certain amount of time, while the line shows the mean. Click on the plot for a larger view showing the outliers.

  • The plot on the right shows the linear regression calculated from the measurements. Each point represents a sample, though here it shows the total time for the sample rather than time per iteration. The line is the line of best fit for these measurements.

• See the documentation for more details on the additional statistics.
