Detailed Description

template<typename Char>
class fmt::BasicWriter< Char >

This template provides operations for formatting and writing data into a character stream. The output is stored in a buffer provided by a subclass such as :class:fmt::BasicMemoryWriter.

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

+------—+-------------------—+ | Type | Definition | +=========+======================+ | Writer | BasicWriter<char> | +------—+-------------------—+ | WWriter | BasicWriter<wchar_t> | +------—+-------------------—+

template<typename Char>
void fmt::BasicWriter< Char >::write ( BasicCStringRef< Char >  format,
ArgList  args 
)
inline

Writes formatted data.

args* is an argument list representing arbitrary arguments.

Example**::

MemoryWriter out; out.write("Current point:\n"); out.write("({:+f}, {:+f})", -3.14, 3.14);

This will write the following output to the out object:

.. code-block:: none

Current point: (-3.140000, +3.140000)

The output can be accessed using :func:data(), :func:c_str or :func:str methods.
