Helper classes

std::uses_allocator<std::function>

 

template< class F, class Alloc > void assign( F&& f, const Alloc& alloc );		(since C++11) (until C++17)

Initializes the target with f. alloc is used to allocate memory for any internal data structures that the function might use.

Equivalent to function(allocator_arg, alloc, std::forward<F>(f)).swap(*this)

Parameters

f	-	callable function to initialize the target with
alloc	-	allocator to use to allocate memory for the internal data structures

Return value

(none)

Exceptions

(none)
