Struct template constructible

boost::type_erasure::constructible

Synopsis

// In header: <boost/type_erasure/any.hpp>

template<typename Sig> 
struct constructible {
};

Description

The constructible concept enables calling the constructor of a type contained by an any. Sig should be a function signature. The return type is the placeholder specifying the type to be constructed. The arguments are the argument types of the constructor. The arguments of Sig may be placeholders.

	Note
	constructible may not be specialized and may not be passed to call as it depends on the implementation details of any.
