The last data block must have\n * mode Z_FINISH (or `true`). That will flush internal pending buffers and call\n * [[Inflate#onEnd]]. For interim explicit flushes (without ending the stream) you\n * can use mode Z_SYNC_FLUSH, keeping the decompression context.\n *\n * On fail call [[Inflate#onEnd]] with error code and return false.\n *\n * We strongly recommend to use `Uint8Array` on input for best speed (output\n * format is detected automatically).
