Defines the usable/required traits when creating a DynTrait<Pointer<()>,ThisInterfaceType> from a type that implements ImplType<Interface= ThisInterfaceType > .

This trait can only be implemented within the impl_InterfaceType macro, giving a default value to each associated type, so that adding associated types is not a breaking change.

The value of every associated type is True/False.

On True,the trait would be required by and usable in DynTrait.

On False,the trait would not be required by and not usable in DynTrait.

Example


use abi_stable::{
    StableAbi,
    impl_InterfaceType,
    erased_types::InterfaceType,
    type_level::bools::*,
};

#[repr(C)]
#[derive(StableAbi)]
pub struct FooInterface;

impl_InterfaceType!{
    impl InterfaceType for FooInterface {
        type Clone=True;

        type Debug=True;
