◆ expr_storage_t

template<class T >

using nda::clef::expr_storage_t = typename detail::expr_storage_impl<T>::type

#include <nda/clef/utils.hpp>

Type trait to determine how a type should be stored in an expression tree, i.e. either by reference or by value?

Rvalue references are copied/moved into the expression tree. Lvalue references are stored as a std::reference_wrapper, unless the compile-time value of nda::clef::force_copy_in_expr is true.

Template Parameters

T	Type to be stored.
