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] Note

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