A type-erased, non-owning view over a random-access sequence.
Declared in <absl/types/any_span.h>
template<typename T>
class AnySpan;Like absl::Span, an AnySpan refers to elements owned elsewhere, but it can wrap any container, array, or view of a compatible element type and can apply a transform to each element on access. It must not outlive the data, transform, or container it refers to.
