[[nodiscard]] void* allocate(std::size_t bytes,
                             std::size_t alignment = alignof(std::max_align_t));
(since C++20)

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.

Equivalent to return do_allocate(bytes, alignment);.

[edit] Exceptions

Throws an exception if storage of the requested size and alignment cannot be obtained.
