public FileStatus Status { get; }

After you call AsyncReadManager.OpenFileAsync, the FileHandle enters the FileStatus.Pending state. Once the open operation completes, the status changes to either FileStatus.Open or FileStatus.Closed (if the file failed to open).

Note: When the close operation completes, the FileHandle is disposed and becomes invalid. You can use the JobHandle returned by FileHandle.Close to check for close operation completion.
