Why Zserio templates are not implemented by C++ templates?

[mikir]

The main problem why Zserio templates are not implemented by C++ templates are primitives types which can be used as template parameters.

Consider the following easy Zserio template code:

struct MyTemplate<TYPE>
{
    TYPE x;
};

If template parameter is a primitive Zserio type (uint8, string, bool), there is no way how to deduce corresponded write and read methods from them. For example, primitive types uint16 and varuin16 have the same C++ mapping to uint16_t type but different coding to the bit stream. Therefore for each possible primitive type, there would have to be a corresponded class wrapper available in the runtime library, e.g. UInt8TemplateParameter, BoolTemplateParameter, etc..
