Detailed Description

template<typename Char, typename Allocator = std::allocator<Char>>
class fmt::BasicMemoryWriter< Char, Allocator >

This class template provides operations for formatting and writing data into a character stream. The output is stored in a memory buffer that grows dynamically.

You can use one of the following typedefs for common character types and the standard allocator:

+------------—+--------------------------------------------------—+ | Type | Definition | +===============+=====================================================+ | MemoryWriter | BasicMemoryWriter<char, std::allocator<char>> | +------------—+--------------------------------------------------—+ | WMemoryWriter | BasicMemoryWriter<wchar_t, std::allocator<wchar_t>> | +------------—+--------------------------------------------------—+

Example**::

MemoryWriter out; out << "The answer is " << 42 << "\n"; out.write("({:+f}, {:+f})", -3.14, 3.14);

This will write the following output to the out object:

.. code-block:: none

The answer is 42 (-3.140000, +3.140000)

The output can be converted to an std::string with out.str() or accessed as a C string with out.c_str().
