A ``printf`` argument formatter based on the `curiously recurring template

pattern <http://en.wikipedia.org/wiki/Curiously_recurring_template_pattern>`_.
|
||||
|
||||
To use `~fmt::BasicPrintfArgFormatter` define a subclass that implements some
|
||||
or all of the visit methods with the same signatures as the methods in
|
||||
`~fmt::ArgVisitor`, for example, `~fmt::ArgVisitor::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 `~fmt::ArgVisitor::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 `~fmt::BasicPrintfArgFormatter` or its
|
||||
superclass will be called.
