- use C++ type style:
- Type& val
- Type* val
- use
std::move for forward std::string (and other big [not fundamental] types)
constructor(std::string string)
: field(std::move(string))
- use
const & for [big type] argument
- use
universal reference to forward template argument
- use
std::forward to forward template argument
auto function(std::vector<big_type>& list, big_type case1, const big_type& case2, auto&& case3)
{
list.push_back(std::move(case1)) // one copy/only move, but call function(list, std::move(val), ..., ...)
list.push_back(case2) // always one copy
list.push_back(std::forward<decltype(case3)>(case3)) // same case1 but have other features
}auto function(big_type case1, const big_type& case2, auto&& case3)
{
case1.readonly_func() // (( always one copy
case2.readonly_func() // )) no copy
case3.readonly_func() // )) no copy
}
