DLDataType

structExperimental#include <rlmesh.h>[source]

\brief The data type the tensor can hold. The data type is assumed to follow the native endian-ness. An explicit error message should be raised when attempting to export an array with non-native endianness

struct

Examples

float: type_code = 2, bits = 32, lanes = 1
float4(vectorized 4 float): type_code = 2, bits = 32, lanes = 4
int8: type_code = 0, bits = 8, lanes = 1
std::complex<float>: type_code = 5, bits = 64, lanes = 1
bool: type_code = 6, bits = 8, lanes = 1 (as per common array library convention, the underlying storage size of bool is 8 bits)

Fields

code\brief Type code of base types.
bits\brief Number of bits, common choices are 8, 16, 32.
lanes\brief Number of lanes in the type, used for vector types.

code

uint8_t code

\brief Type code of base types. We keep it uint8_t instead of DLDataTypeCode for minimal memory footprint, but the value should be one of DLDataTypeCode enum values.

bits

field[source]

uint8_t bits

\brief Number of bits, common choices are 8, 16, 32.

lanes

field[source]

uint16_t lanes

\brief Number of lanes in the type, used for vector types.
