Overloads
| TensorSpan<T>(Array) |
Creates a new TensorSpan<T> over the provided Array. The new TensorSpan<T> will have a rank of 1 and a length equal to the length of the provided Array. |
| TensorSpan<T>(T[], Int32, ReadOnlySpan<IntPtr>, ReadOnlySpan<IntPtr>) |
Creates a new span over the portion of the target array beginning at 'start' index and ending at 'end' index (exclusive). |
| TensorSpan<T>(T*, IntPtr, ReadOnlySpan<IntPtr>, ReadOnlySpan<IntPtr>) |
Creates a new span over the target unmanaged buffer. Clearly this is quite dangerous, because the length is not checked. But if this creation is correct, then all subsequent uses are correct. |
| TensorSpan<T>(Array, ReadOnlySpan<Int32>, ReadOnlySpan<IntPtr>, ReadOnlySpan<IntPtr>) |
Creates a new TensorSpan<T> over the provided Array using the specified start offsets, lengths, and strides. If the strides are not provided, they will be automatically calculated. |
| TensorSpan<T>(Array, ReadOnlySpan<NIndex>, ReadOnlySpan<IntPtr>, ReadOnlySpan<IntPtr>) |
Creates a new TensorSpan<T> over the provided Array using the specified start offsets, lengths, and strides. If the strides are not provided, they will be automatically calculated. |
| TensorSpan<T>(T[], Index, ReadOnlySpan<IntPtr>, ReadOnlySpan<IntPtr>) |
Creates a new span over the portion of the target array beginning at 'start' index and ending at 'end' index (exclusive). |
| TensorSpan<T>(T*, IntPtr) |
Creates a new span over the target unmanaged buffer. Clearly this is quite dangerous the length is not checked. But if this creation is correct, then all subsequent uses are correct. |
| TensorSpan<T>(T[]) |
Creates a new span over the entirety of the target array. |
| TensorSpan<T>(Span<T>) |
Creates a new TensorSpan<T> over the provided Span<T>. The new TensorSpan<T> will have a rank of 1 and a length equal to the length of the provided Span<T>. |
| TensorSpan<T>(Span<T>, ReadOnlySpan<IntPtr>, ReadOnlySpan<IntPtr>) |
Creates a new TensorSpan<T> over the provided Span<T> using the specified lengths and strides. If the strides are not provided, they will be automatically calculated. |
