- A dynamically growing memory buffer for trivially copyable/constructible types

- +================+==============================+
- | memory_buffer | basic_memory_buffer<char> |
- +----------------+------------------------------+
- | wmemory_buffer | basic_memory_buffer<wchar_t> |
- +----------------+------------------------------+
-
- **Example**::
-
- fmt::memory_buffer out;
- format_to(out, "The answer is {}.", 42);
-
- This will append the following output to the ``out`` object:
-
- .. code-block:: none
-
- The answer is 42.
-
- The output can be converted to an ``std::string`` with ``to_string(out)``.
