std::pmr::polymorphic_allocator<T>::new_object (3) - Linux Man Pages
template< class U, class CtorArgs... > (since C++20)
U* new_object( CtorArgs&&... ctor_args );
Allocates and constructs an object of type U.
ctor_args - the arguments to forward to the the constructor of U
A pointer to the allocated and constructed object.
This function was introduced for use with the fully-specialized allocator std::polymorphic_allocator<>, but it may be useful in any specialization as a shortcut to avoid having to rebind from std::polymorphic_allocator<T> to std::polymorphic_allocator<U>, and having to call allocate, construct, and deallocate individually.
Since U is not deduced, it must be provided as a template argument when calling this function.
May throw any exceptions thrown by the call to allocate_object or the constructor of U.
allocate_bytes Allocate raw aligned memory from the underlying resource
allocate_object Allocates raw memory suitable for an object or an array
