Detailed Description

template<typename T>
struct axom::type_identity< T >

Maps a type to itself in a non-deduced context.

This is an Axom-local equivalent of C++20's std::type_identity for C++17. Its primary use is to suppress template argument deduction for a function parameter. A parameter declared as type_identity_t<T> does not participate in deducing T, so T is taken from the explicit template argument or from another parameter, and the argument here is implicitly converted.
