Trait 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 new methods to be found on the peer type. If the C++ 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 new method on the <my subclass name>Cpp type, passing peer_holder as the first argument.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
