static void* std::allocator_traits< allocator< void > >::allocate ( allocator_type ,
size_type  ,
const void *  = nullptr 
)
staticdelete

allocate is ill-formed for allocator<void>

void *  ,
size_type   
)
staticdelete

deallocate is ill-formed for allocator<void>

max_size is ill-formed for allocator<void>

template<typename _Up , typename... _Args>
static constexpr void std::allocator_traits< allocator< void > >::noexcept ( std::is_nothrow_constructible< _Up, _Args...>::value  )
inlinestatic

Construct an object of type _Up

Parameters
__aAn allocator.
__pPointer to memory of suitable size and alignment for an object of type _Up.
__argsConstructor arguments.

Calls __a.construct(__p, std::forward<_Args>(__args)...) in C++11, C++14 and C++17. Changed in C++20 to call std::construct_at(__p, std::forward<_Args>(__args)...) instead.

template<typename _Up >
static constexpr void std::allocator_traits< allocator< void > >::noexcept ( is_nothrow_destructible< _Up >::value  )

Destroy an object of type _Up

Parameters
__aAn allocator.
__pPointer to the object to destroy

Invokes the destructor for *__p.

static constexpr allocator_type std::allocator_traits< allocator< void > >::select_on_container_copy_construction ( const allocator_type __rhs)

Obtain an allocator to use when copying a container.

Parameters
__rhsAn allocator.
Returns
__rhs
