Collaboration diagram for Type Traits & Metaprogramming:

Classes
struct	qb::crtp< T >
	Base class for implementing the Curiously Recurring Template Pattern (CRTP). More...
struct	qb::is_container< T >
	Type trait to check if a type T is a container. More...
struct	qb::remove_reference_if< T, cond >
	Conditionally removes a reference from type T if cond is true. More...

Typedef Documentation

Void

template<typename...>

using qb::Void = void

Helper alias to void for SFINAE purposes.

Template Parameters

Args	Ignored template parameters.

Used in std::enable_if and other SFINAE contexts to create a dependent void type.
