FlattenedLength	Gets the number of items in the span.
HasAnyDenseDimensions	Gets a value that indicates whether the current tensor has any dimension span where IsDense is `true`.
IsDense	Gets a value that indicates whether the current tensor is dense.
IsEmpty	Gets a value indicating whether this TensorSpan<T> is empty.
IsPinned	Gets a value that indicates whether the underlying buffer is pinned.
Item[ReadOnlySpan<IntPtr>]	Returns a reference to specified element of the ReadOnlyTensorSpan.
Item[ReadOnlySpan<NIndex>]	Returns a reference to specified element of the ReadOnlyTensorSpan.
Item[ReadOnlySpan<NRange>]	Returns 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>.

Methods

CastUp<TDerived>(ReadOnlyTensorSpan<TDerived>)	Casts a tensor span of `TDerived` to a tensor span of `T`.
CopyTo(TensorSpan<T>)	Copies the contents of the tensor into a destination tensor span.
Equals(Object)	Obsolete. Calls to this method are not supported.
FlattenTo(Span<T>)	Flattens the contents of this span into the provided Span<T>.
GetDimensionSpan(Int32)	Returns a span that can be used to access the flattened elements for a given dimension.
GetEnumerator()	Gets an enumerator for the readonly tensor span.
GetHashCode()	Obsolete. Calls to this method are not supported.
GetPinnableReference()	Returns a reference to the 0th element of the ReadOnlyTensorSpan. If the ReadOnlyTensorSpan is empty, returns null reference.
GetSpan(ReadOnlySpan<IntPtr>, Int32)	Return a span that starts at the specified index and contains the specified number of items.
GetSpan(ReadOnlySpan<NIndex>, Int32)	Return a span that starts at the specified index and contains the specified number of items.
Slice(ReadOnlySpan<IntPtr>)	Forms a slice out of the current tensor that begins at a specified index.
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 the string representation of the tensor span.
TryCopyTo(TensorSpan<T>)	Attempts to copy the contents of this tensor into a destination tensor span and returns a value to indicate whether or not the operation succeeded.
TryFlattenTo(Span<T>)	Flattens the contents of this span into the provided Span<T>.
TryGetSpan(ReadOnlySpan<IntPtr>, Int32, ReadOnlySpan<T>)	Tries to return a span that starts at the specified index and contains the specified number of items.
TryGetSpan(ReadOnlySpan<NIndex>, Int32, ReadOnlySpan<T>)	Tries to return a span that starts at the specified index and contains the specified number of items.

Operators

Equality(ReadOnlyTensorSpan<T>, ReadOnlyTensorSpan<T>)	Returns a value that indicates whether two tensor spans are equal.
Implicit(T[] to ReadOnlyTensorSpan<T>)
Inequality(ReadOnlyTensorSpan<T>, ReadOnlyTensorSpan<T>)	Returns a value that indicates whether two tensor spans are not equal.

Extension Methods

BroadcastTo<T>(ReadOnlyTensorSpan<T>, TensorSpan<T>)	Broadcast the data from `source` to `destination`.
Reshape<T>(ReadOnlyTensorSpan<T>, ReadOnlySpan<IntPtr>)	Reshapes the `tensor` tensor to the specified `lengths`. If one of the lengths is -1, it will be calculated automatically. Does not change the length of the underlying memory nor does it allocate new memory. If the new shape is not compatible with the old shape, an exception is thrown.
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>)	Removes all dimensions of length one from the `tensor`.
SqueezeDimension<T>(ReadOnlyTensorSpan<T>, Int32)	Removes axis of length one from the `tensor` for the given `dimension`. If the dimension is not of length one it will throw an exception.
ToString<T>(ReadOnlyTensorSpan<T>, ReadOnlySpan<IntPtr>)	Creates a String representation of the ReadOnlyTensorSpan<T>."/>
TryBroadcastTo<T>(ReadOnlyTensorSpan<T>, TensorSpan<T>)	Broadcast the data from `tensor` to the smallest broadcastable shape compatible with `destination` and stores it in `destination` If the shapes are not compatible, false is returned.
Unsqueeze<T>(ReadOnlyTensorSpan<T>, Int32)	Insert a new dimension of length 1 that will appear at the dimension position.
