Public Members

int32_t type_index

type index of the object.

Note

The type index of Object and Any are shared in FFI.

uint32_t zero_padding

padding, must set to zero for values other than small string.

uint32_t small_str_len

Length of small string, with a max value of 7.

We keep small str to start at next 4 bytes to ensure alignment when accessing the small str content.

int64_t v_int64

integers

double v_float64

floating-point numbers

void *v_ptr

typeless pointers

const char *v_c_str

raw C-string

TVMFFIObject *v_obj

ref counted objects

DLDataType v_dtype

data type

DLDevice v_device

device

char v_bytes[8]

small string

uint64_t v_uint64

uint64 repr mainly used for hashing
