💖 std::experi...do_allocate(3) 💖

okay bestie, this page is from the C++ Standard Libary manual, and it’s giving pure-virtual allocation energy. No cap. Here’s the whole thing, with zero facts dropped. 🫶

✨ NAME ✨

std::experimental::pmr::memory_resource::do_allocate — and yes, the page says it again: std::experimental::pmr::memory_resource::do_allocate.

📝 Synopsis 📝

virtual void* do_allocate( std::size_t bytes, std::size_t alignment ) = 0;

This is the (library fundamentals TS) version, just so you know. ✨

Allocates storage with a size of at least bytes bytes. The returned storage is aligned to the specified alignment if such alignment is supported, and to alignof(std::max_align_t) otherwise.

alignment shall be a power of two. That’s the rule, bestie — not a vibe suggestion. 💅

💥 Exceptions 💥

Throws an exception if storage of the requested size and alignment cannot be obtained. So if it can’t get the goods, it throws. Periodt. 😭
