Basic usage

You can measure the time of easy processing.

use HHPack\Performance\PerformanceWatcher;
use HHPack\Performance\TimeWatcher;
use HHPack\Performance\MemoryWatcher;
use HHPack\Performance\Result\WatchedResult;

$watcher = PerformanceWatcher::fromItems([
    Pair { 'time', new TimeWatcher() },
    Pair { 'memory', new MemoryWatcher() }
]);

$watcher->start();
$watcher->stop();

$texts = $watcher->result()->mapWithKey(($key, $result) ==> {
    return sprintf("%s: %s", $key, (string) $result->value());
})->values();

foreach ($texts as $text) {
    echo $text, PHP_EOL;
}

Benchmark

use HHPack\Performance as bench;

function sync_benchmarker() : void
{
    bench\sync()->times(10)->run(() ==> {
        usleep(2000);
    });
}
sync_benchmarker();

or

use HHPack\Performance as bench;

async function async_benchmarker_main() : Awaitable<void>
{
    await bench\async()->times(10)->run(async () ==> {
        await \HH\Asio\usleep(2000);
    });
}

\HH\Asio\join(async_benchmarker_main());
