std::function
template< class F, class Alloc >
void assign( F&& f, const Alloc& alloc );
(since C++11) void assign( F&& f, const Alloc& alloc );
(removed in C++17)
Initializes the target with f. The alloc is used to allocate memory for any internal data structures that the function might use.
Equivalent to function(std::allocator_arg, alloc, std::forward <F>(f)).swap(*this);.
