Casts a tensor span of TDerived to a tensor span of T.
public:
generic <typename TDerived>
where TDerived : class, T static System::Numerics::Tensors::ReadOnlyTensorSpan<T> CastUp(System::Numerics::Tensors::ReadOnlyTensorSpan<TDerived> % items);public static System.Numerics.Tensors.ReadOnlyTensorSpan<T> CastUp<TDerived>(in System.Numerics.Tensors.ReadOnlyTensorSpan<TDerived> items) where TDerived : class, T;static member CastUp : ReadOnlyTensorSpan -> System.Numerics.Tensors.ReadOnlyTensorSpan<'T>Public Shared Function CastUp(Of TDerived As {Class, T}) (ByRef items As ReadOnlyTensorSpan(Of TDerived)) As ReadOnlyTensorSpan(Of T)Type Parameters
- TDerived
The element type of the source tensor span, which must be derived from T.
Parameters
- items
- ReadOnlyTensorSpan<TDerived>
The source tensor span. No copy is made.
Returns
A tensor span with elements cast to the new type.
Remarks
This method uses a covariant cast, producing a tensor span that shares the same memory as the source. The relationships expressed in the type constraints ensure that the cast is a safe operation.
