CLI::enums Namespace Reference

Functions
template<typename T , typename = typename std::enable_if<std::is_enum<T>::value>::type>
std::ostream &	operator<< (std::ostream &in, const T &item)
	output streaming for enumerations

Detailed Description

Include the items in this namespace to get free conversion of enums to/from streams. (This is available inside CLI as well, so CLI11 will use this without a using statement).
