ProfilerUnsafeUtility.TimestampToNanosecondsConversionRatio

说明

获取转换比率，从 Profiler 时间戳到纳秒。

用于转换使用 GetTimestamp 获取的 Profiler 时间戳值到纳秒。

using Unity.Profiling.LowLevel.Unsafe;

public class Example
{
    public static long ElapsedNanoseconds(long startTimestamp)
    {
        long now = ProfilerUnsafeUtility.Timestamp;
        var conversionRatio = ProfilerUnsafeUtility.TimestampToNanosecondsConversionRatio;
        return (now - startTimestamp) * conversionRatio.Numerator / conversionRatio.Denominator;
    }
}
