Cause
-----

An explicit interface property implementation is annotated with the ``[Export]``
attribute. Properties that implement an interface explicitly can't be exported.

Rule description
----------------

Godot doesn't allow exporting explicit interface property implementations.
When an interface member is implemented explicitly, the member is hidden and
consumers can't access them unless the type is converted to the interface first.
Explicitly implemented members can also share the same name of other members in
the type, so it could create naming conflicts with other exported members.

.. code-block:: csharp

    public interface MyInterface
    {
        public int MyProperty { get; set; }
    }

    public class MyNode1 : Node, MyInterface
    {
        // The property can be exported because it implements the interface implicitly.
        [Export]
        public int MyProperty { get; set; }
    }

    public class MyNode2 : Node, MyInterface
    {
        // The property can't be exported because it implements the interface explicitly.
        [Export]
        int MyInterface.MyProperty { get; set; }
    }

How to fix violations
---------------------

To fix a violation of this rule, implement the interface implicitly or remove
the ``[Export]`` attribute.

When to suppress warnings
-------------------------

Do not suppress a warning from this rule. Explicit interface property implementations
can't be exported so they will be ignored by Godot, resulting in runtime errors.
