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.
