Below is code that adds elements to a vector containing a std::pair
std::vector<std::pair<std::string, std::type_index>> args_;
template <class T>
inline OperationEntry& setArg(const std::string& name)
{
args_.push_back({name, typeid(T)});
return *this;
}
How do I add elements to a vector containing a std::tuple
?
std::vector<std::tuple<std::string, std::type_index, Attribute>> args_;
template <class T>
inline OperationEntry& setArg(const std::string& name, Attribute value = Attribute())
{
args_.push_back({name, typeid(T), value});
return *this;
}
I tried args_.push_back(std::make_tuple(name, typeid(T), value));
I am getting this error:
[GCC] converting to
‘std::vector<std::tuple<std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> >, std::type_index,
mv::Attribute> >::value_type {aka
std::tuple<std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> >, std::type_index, mv::Attribute>}’ from
initializer list would use explicit constructor ‘constexpr std::tuple<
<template-parameter-1-1> >::tuple(_UElements&& ...) [with _UElements =
{const std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> >&, const std::type_info&, mv::Attribute&};
<template-parameter-2-2> = void; _Elements =
{std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> >, std::type_index, mv::Attribute}]’
