Macro: HIAI_REGISTER_DATA_TYPE

Provides automatic serialization and deserialization mechanisms for various user-defined data types. This macro is defined in data_type_reg.h.

  • This API must be registered on both the host side and the device side.
  • Due to the restrictions of Cereal, do not use the long double type in the struct body. To ensure running across platforms (for example, from Windows to Linux), the portable type is recommended for the struct members, for example, int32_t, in the struct body.
  • Due to the restrictions of Cereal, the struct body needs to use the shared pointer.
