basic_memory_buffer< T, SIZE, Allocator > Class Template Reference

Detailed Description

template<typename T, size_t SIZE = inline_buffer_size, typename Allocator = std::allocator<T>>
class basic_memory_buffer< T, SIZE, Allocator >

\rst A dynamically growing memory buffer for trivially copyable/constructible types with the first SIZE elements stored in the object itself.

You can use the memory_buffer type alias for char instead.

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). \endrst
