struct	iox2::legacy::in_place_index< N >
	helper struct to perform an emplacement at a predefined index in the constructor of a variant More...

class	iox2::legacy::variant< Types >
	Variant implementation from the C++17 standard with C++11. The interface is inspired by the C++17 standard but it has changes in get and emplace since we are not allowed to throw exceptions. More...
