simplebench 0.1.0

SimpleBench

This is a small benchmarking library for the D programming language. I wrote it when I started playing with the D programming language because I needed simple benchmarking utilities that where not available at that time.

The library is heavily inspired by the integrated benchmarking utilities of the Rust compiler.

Installation

USAGE

Example:

import std.stdio;
import std.json;

import simplebench;

immutable N = 25;
// Functions to bench
ulong fib_rec(immutable int n){
 ...
}
// Function to bench
ulong fib_for_loop(immutable int n) {
    ...
}

// The proper test function
void test_fib_rec(ref Bencher bencher){
  int n=N; // Init variables, allocate memory ...
  bencher.iter((){
      return fib_rec(n); // The real code to bench
  });
}

void main()
{
  // The test function have to be static
  static void test_fib_for_loop(ref Bencher bencher){
    int n=N;
    bencher.iter((){
        return fib_for_loop(n);
    });
  }

  assert(fib_for_loop(N) == fib_rec(N));
  // Run the benchmarks
  auto br = BenchMain!(test_fib_rec, test_fib_for_loop);
  // Convert the results to JSON
  writeln(br.toJSON.toPrettyString);
