I’m dealing with a fairly uniform vendor-provided API, and would like to check — and handle — any failures in a unified fashion too. To that end, I wrote the following wrapper:

I am working with a third party library which provides a Numeric class that must be templated with precision and scale arguments. Unfortunately, within the context of the library I am creating, the precision and scale is not known until runtime, so I need to create a runtime mapping of those values to their respective templated functions.

assume a template variable in data.h:

I would like to update conversion functions which have the following signatures:

For compile time checker which tests whether a type T is std::list I’ve came up with this template:
