-    * *not supported yet*: Blob, File, FileList, ImageBitmap, ImageData, and ArrayBuffer, but typed arrays are supported without major issues, but u/int8, u/int16, and u/int32 are the only safely suppored (right now).

     * *not possible to implement*: the `{transfer: []}` option can be passed but it's completely ignored.
