Represents a contiguous region of arbitrary memory. Unlike arrays, it can point to either managed or native memory, or to memory allocated on the stack. It is type-safe and memory-safe.

Constructors
ReadOnlyTensorSpan<T>(Array) |
Creates a new ReadOnlyTensorSpan<T> over the provided Array. The new ReadOnlyTensorSpan<T> will have a rank of 1 and a length equal to the length of the provided Array. |
ReadOnlyTensorSpan<T>(Array, ReadOnlySpan<Int32>, ReadOnlySpan<IntPtr>, ReadOnlySpan<IntPtr>) |
Creates a new ReadOnlyTensorSpan<T> over the provided Array using the specified start offsets, lengths, and strides. If the strides are not provided, they will be automatically calculated. |
ReadOnlyTensorSpan<T>(Array, ReadOnlySpan<NIndex>, ReadOnlySpan<IntPtr>, ReadOnlySpan<IntPtr>) |
Creates a new ReadOnlyTensorSpan<T> over the provided Array using the specified start offsets, lengths, and strides. If the strides are not provided, they will be automatically calculated. |
ReadOnlyTensorSpan<T>(ReadOnlySpan<T>) |
Creates a new ReadOnlyTensorSpan<T> over the provided ReadOnlySpan<T>. The new ReadOnlyTensorSpan<T> will have a rank of 1 and a length equal to the length of the provided ReadOnlySpan<T>. |
ReadOnlyTensorSpan<T>(ReadOnlySpan<T>, ReadOnlySpan<IntPtr>, ReadOnlySpan<IntPtr>) |
Creates a new ReadOnlyTensorSpan<T> over the provided Span<T> using the specified lengths and strides. If the strides are not provided, they will be automatically calculated. |
ReadOnlyTensorSpan<T>(T*, IntPtr) |
Creates a new span over the target unmanaged buffer. |
ReadOnlyTensorSpan<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. |
ReadOnlyTensorSpan<T>(T[]) |
Creates a new span over the entirety of the target array. |
ReadOnlyTensorSpan<T>(T[], Index, ReadOnlySpan<IntPtr>, ReadOnlySpan<IntPtr>) |
Creates a new span over the portion of the target array beginning at the specified start index and ending at the end index (exclusive). |
ReadOnlyTensorSpan<T>(T[], Int32, ReadOnlySpan<IntPtr>, ReadOnlySpan<IntPtr>) |
Creates a new span over the portion of the target array beginning at the specified start index and ending at the end index (exclusive). |
Properties
Empty |
Gets a 0-length read-only span whose base is the |
FlattenedLength |
Gets the number of items in the span. |
IsEmpty |
Gets a value indicating whether this TensorSpan<T> is empty. |
Item[ReadOnlySpan<IntPtr>] |
Gets a reference to specified element of the ReadOnlyTensorSpan. |
Item[ReadOnlySpan<NIndex>] |
Gets a reference to specified element of the ReadOnlyTensorSpan. |
Item[ReadOnlySpan<NRange>] |
Gets a slice of the ReadOnlyTensorSpan. |
Lengths |
Gets the length of each dimension in this TensorSpan<T>. |
Rank |
Gets the rank, or number of dimensions, of this TensorSpan<T>. |
Strides |
Gets the strides of this TensorSpan<T>. |
Methods
CastUp<TDerived>(ReadOnlyTensorSpan<TDerived>) |
Casts a read-only span of |
CopyTo(TensorSpan<T>) |
Copies the contents of this read-only span into destination span. If the source and destinations overlap, this method behaves as if the original values are in a temporary location before the destination is overwritten. |
Equals(Object) |
Obsolete.
This method is not supported as spans cannot be boxed. To compare two spans, use operator ==. |
FlattenTo(Span<T>) |
Flattens the contents of this span into the provided Span<T>. |
GetEnumerator() |
Gets an enumerator for this span. |
GetHashCode() |
Obsolete.
This method is not supported as spans cannot be boxed. |
GetPinnableReference() |
Returns a reference to the 0th element of the ReadOnlyTensorSpan. |
Slice(ReadOnlySpan<NIndex>) |
Returns a reference to specified element of the TensorSpan. |
Slice(ReadOnlySpan<NRange>) |
Forms a slice out of the given span. |
ToString() |
Returns a String with the name of the type and the number of elements. |
TryCopyTo(TensorSpan<T>) |
Copies the contents of this read-only span into destination span. If the source and destinations overlap, this method behaves as if the original values are in a temporary location before the destination is overwritten. |
TryFlattenTo(Span<T>) |
Flattens the contents of this span into the provided Span<T>. |
Operators
Equality(ReadOnlyTensorSpan<T>, ReadOnlyTensorSpan<T>) |
Compares two System.Numerics.Tensors.ReadOnlyTensorSpan<T> structs for equality. |
Implicit(T[] to ReadOnlyTensorSpan<T>) | |
Inequality(ReadOnlyTensorSpan<T>, ReadOnlyTensorSpan<T>) |
Compares two System.Numerics.Tensors.ReadOnlyTensorSpan<T> structs for inequality. |
Extension Methods
BroadcastTo<T>(ReadOnlyTensorSpan<T>, TensorSpan<T>) |
Broadcasts the data from |
Reshape<T>(ReadOnlyTensorSpan<T>, ReadOnlySpan<IntPtr>) |
Reshapes the |
SequenceEqual<T>(ReadOnlyTensorSpan<T>, ReadOnlyTensorSpan<T>) |
Determines whether two sequences are equal by comparing the elements using IEquatable{T}.Equals(T). |
Squeeze<T>(ReadOnlyTensorSpan<T>, Int32) | |
ToString<T>(ReadOnlyTensorSpan<T>, ReadOnlySpan<IntPtr>) |
Creates a String representation of the ReadOnlyTensorSpan<T>. |
TryBroadcastTo<T>(ReadOnlyTensorSpan<T>, TensorSpan<T>) |
Broadcasts the data from |
Unsqueeze<T>(ReadOnlyTensorSpan<T>, Int32) |
Inserts a new dimension of length 1 that will appear at the dimension position. |
