Microsoft Guidelines Support Library
The Guideline Support Library (GSL) contains functions and types that are suggested for use by the C++ Core Guidelines maintained by the Standard C++ Foundation. This package contains Microsoft's implementation of GSL.
The library includes types like span<T>, string_span, owner<> and others.
The entire implementation is provided inline in the headers under the gsl directory. The implementation generally assumes a platform that implements C++14 support.
