Extracts elements at specified positions from a tuple container.

**Table 1** Template parameters
Parameter	Description
N	Constant during building, which indicates the index of the element to be extracted. The index starts from 0 and the value range is [0, 64).
Tps...	Template parameter package passed to the tuple. The number of tuple parameters is in the range of (0, 64]. For the Atlas A3 training products/Atlas A3 inference products, the supported data types are bool, int4b_t, int8_t, uint8_t, int16_t, uint16_t, half, bfloat16_t, int32_t, uint32_t, float, int64_t, uint64_t, LocalTensor and GlobalTensor. For the Atlas A2 training products/Atlas A2 inference products, the supported data types are bool, int4b_t, int8_t, uint8_t, int16_t, uint16_t, half, bfloat16_t, int32_t, uint32_t, float, int64_t, uint64_t, LocalTensor and GlobalTensor.
t	Tuple object, which can be a left-value reference, a constant left-value reference, or a right-value reference.

The get function supports only the const and constexpr constant indexes. The index value range is [0, 64).

Element in the corresponding position in the tuple object

AscendC::Std::tuple<uint32_t, float, bool> test{11, 2.2, true};
uint32_t const_uint32_t = AscendC::Std::get<0>(test);
