ProfilerMarkerData

描述

描述可与样本关联的 Profiler 元数据参数。

与 ProfilerUnsafeUtility.BeginSampleWithMetadata 方法一起使用。Type 值定义了 Ptr 指向的数据类型。该值必须是 ProfilerMarkerDataType 枚举值。

class Example
{
    static IntPtr MakeMarkerWithIntMetadata(string name, string paramName)
    {
        var handle = ProfilerUnsafeUtility.CreateMarker(name, ProfilerUnsafeUtility.CategoryScripts, MarkerFlags.Default, 1);
        ProfilerUnsafeUtility.SetMarkerMetadata(handle, 0, paramName, (byte)ProfilerMarkerDataType.Int32, (byte)ProfilerMarkerDataUnit.Count);
        return handle;
    }

    static readonly IntPtr markerHandle = MakeMarkerWithIntMetadata("MyMarker", "Work Idx");

    static unsafe void DoWork(int num)
    {
        var metadata = stackalloc ProfilerMarkerData[1];
        metadata[0].Type = (byte)ProfilerMarkerDataType.Int32;
        metadata[0].Size = (uint)UnsafeUtility.SizeOf<int>();
        metadata[0].Ptr = UnsafeUtility.AddressOf(ref num);
        ProfilerUnsafeUtility.BeginSampleWithMetadata(markerHandle, 1, metadata);
        //...
        ProfilerUnsafeUtility.EndSample(markerHandle);
    }
