static Ptr ptr_cast (const From_ptr &ptr_to_cast)
 Provides syntactic-sugary way to perform a static_pointer_cast<> from a compatible smart pointer type From_ptr, typically From_ptr::element_type being in the same class hierarchy as Target_ptr::element_type. More...
 
static Const_ptr const_ptr_cast (const From_ptr &ptr_to_cast)
 Identical to ptr_cast() but adds const-ness (immutability) to the pointed-to type. More...
 
static Ptr dynamic_ptr_cast (const From_ptr &ptr_to_cast)
 Equivalent to ptr_cast() but a dynamic_pointer_cast instead of static. More...

Detailed Description

Empty struct suitable as a *_value_set template arg for Config_manager, when a slot requires a Value_set, but you have no config to actually parse there.

In particular, if you have a static Value_set but no corresponding dynamic one, you should provide this as the template arg.
