Detailed Description

template<class T, size_t Extent>
class nostd::span< T, Extent >

Back port of std::span.

See https://en.cppreference.com/w/cpp/container/span for interface documentation.

Note: This provides a subset of the methods available on std::span.

Note: The std::span API specifies error cases to have undefined behavior, so this implementation chooses to terminate or assert rather than throw exceptions.
