Detailed Description

template<typename T>
class PS::span< T >

Simplifed version of std::span (C++20) as we don't support the original one yet.

The naming intentionally follows the STL version to make the future replacement easier with less blame changing. It supports only very basic subset of std::span functionality. TODO: remove as soon as std::span become available.
