std::experi...c_allocator(3)

💅 std::experimental::pmr::polymorphic_allocator::polymorphic_allocator 💅

okay so bestie, you're in the C++ Standard Libary manual — yes, that's the manual name, typo and all, we don't make the rules — and this page is literally all about std::experimental::pmr::polymorphic_allocator::polymorphic_allocator. It's giving constructor main character energy and I'm obsessed. 🫶✨

🌸 NAME 🌸

std::experimental::pmr::polymorphic_allocator::polymorphic_allocator — that's the name, and then the page says it again: std::experimental::pmr::polymorphic_allocator::polymorphic_allocator. say it with your chest, bestie. 💅

✨ Synopsis ✨

polymorphic_allocator() noexcept;
(1)
polymorphic_allocator( const polymorphic_allocator& other ) noexcept
= default; (2)
template< class U >
(3)
polymorphic_allocator( const polymorphic_allocator<U>& other )
noexcept;
polymorphic_allocator( memory_resource* r );
(4)

Constructs a new polymorphic_allocator. lowkey straightforward, highkey essential. 🎀

• 1) Constructs a polymorphic_allocator using the return value of std::experimental::pmr::get_default_resource() as the underlying memory resource.
• 2, 3) Constructs a polymorphic_allocator using other.resource() as the underlying memory resource.
• 4) Constructs a polymorphic_allocator using r as the underlying memory resource. This constructor provides an implicit conversion from memory_resource*.

💖 Parameters 💖

• other — another polymorphic_allocator to copy from. copy from bestie, got it. 🫶
• r — pointer to the memory resource to use. May not be null. 🚨 no nulls allowed, periodt.

😭 Exceptions 😭

• 4) Throws nothing. 🕊️ constructor 4 is literally unbothered.
