Detailed Description

template<function_pointer auto F>
class nngn::delegate_fn< F >

Unique type for a function or member function pointer.

The pointer is fully preserved and not converted to a generic function pointer, so that the call through operator()() can be fully optimized. Being a unique type for each pointer value, it can be used where callable types are required (e.g. for nngn::delegate).

Template Parameters

F	A function or member function pointer.
