NativeArray<T> Returns the frame metadata as a NativeArray.

설명

Retrieves metadata associated with the frame.

Use GetFrameMetaData to retrieve the data blob that was written to the profiler stream with the Profiler.EmitFrameMetaData method.

Use id to identify the metadata from your project or package.
Use tag to distinguish between different data streams.
Use index to retrieve separate data chunks for each Profiler.EmitFrameMetaData called in a frame.
