Function

Obtains the instantiated Layout object.

Prototype

__aicore__ inline constexpr decltype(auto) layout() {}
__aicore__ inline constexpr decltype(auto) layout() const {}

Parameters

None

Returns

Instantiated Layout object.

Restrictions

The Shape and Stride structures passed during the construction of the Layout object must be of the Std::tuple type and meet the usage restrictions of the Std::tuple structure type.

Example

AscendC::Shape<int,int,int> shape = AscendC::MakeShape(10, 20, 30);
AscendC::Stride<int,int,int> stride = AscendC::MakeStride(1, 100, 200);

AscendC::Layout<AscendC::Shape<int, int, int>, AscendC::Stride<int, int, int>> layoutInit(shape, stride);

// Use the layout function to obtain the instantiated object.
constexpr auto& layout = layoutInit.layout();
