Detailed Description

template<typename Impl, typename Char, typename Spec>
class fmt::BasicPrintfArgFormatter< Impl, Char, Spec >

\rst A printf argument formatter based on the curiously recurring template pattern <http://en.wikipedia.org/wiki/Curiously_recurring_template_pattern>_.

To use ~fmtBasicPrintfArgFormatter define a subclass that implements some or all of the visit methods with the same signatures as the methods in ~fmt::ArgVisitor, for example, ~fmtArgVisitor::visit_int(). Pass the subclass as the Impl template parameter. When a formatting function processes an argument, it will dispatch to a visit method specific to the argument type. For example, if the argument type is double then the ~fmtArgVisitor::visit_double() method of a subclass will be called. If the subclass doesn't contain a method with this signature, then a corresponding method of ~fmtBasicPrintfArgFormatter or its superclass will be called. \endrst
