Trait autocxx::subclass::CppPeerConstructor

pub trait CppPeerConstructor<CppPeer: CppSubclassCppPeer>: Sized {
    // Required method
    fn make_peer(
        &mut self,
        peer_holder: CppSubclassRustPeerHolder<Self>
    ) -> UniquePtr<CppPeer>;
}

A trait to be implemented by a subclass which knows how to construct its C++ peer object. Specifically, the implementation here will arrange to call one or other of the make_unique methods to be found on the superclass of the C++ object. If the superclass has a single trivial constructor, then this is implemented automatically for you. If there are multiple constructors, or a single constructor which takes parameters, you’ll need to implement this trait for your subclass in order to call the correct constructor.

Required Methods

fn make_peer( &mut self, peer_holder: CppSubclassRustPeerHolder<Self> ) -> UniquePtr<CppPeer>

Create the C++ peer. This method will be automatically generated for you except in cases where the superclass has multiple constructors, or its only constructor takes parameters. In such a case you’ll need to implement this by calling a make_unique method on the <my subclass name>Cpp type, passing peer_holder as the first argument.
