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 using the #[derive(StableAbi)] and 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 can be.

Implemented<_>,the trait would be required by and usable in DynTrait.
Unimplemented<_>,the trait would not be required by and not usable in DynTrait.

Example


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

#[repr(C)]
#[derive(StableAbi)]
#[sabi(impl_InterfaceType(Clone,Debug))]
pub struct FooInterface;

/*
The `#[sabi(impl_InterfaceType(Clone,Debug))]` helper attribute 
(as part of #[derive(StableAbi)]) above is roughly equivalent to this impl:

impl InterfaceType for FooInterface {
    type Clone= Implemented<trait_marker::Clone>;

    type Debug= Implemented<trait_marker::Debug>;

    /////////////////////////////////////    
    //// defaulted associated types
    /////////////////////////////////////

    // Changing this to require/unrequire in minor versions,is an abi breaking change.
    // type Send= Unimplemented<trait_marker::Send>;

    // Changing this to require/unrequire in minor versions,is an abi breaking change.
    // type Sync= Unimplemented<trait_marker::Sync>;

    // type Iterator= Unimplemented<trait_marker::Iterator>;

    // type DoubleEndedIterator= Unimplemented<trait_marker::DoubleEndedIterator>;

    // type Default= Unimplemented<trait_marker::Default>;

    // type Display= Unimplemented<trait_marker::Display>;

    // type Serialize= Unimplemented<trait_marker::Serialize>;

    // type Eq= Unimplemented<trait_marker::Eq>;

    // type PartialEq= Unimplemented<trait_marker::PartialEq>;

    // type Ord= Unimplemented<trait_marker::Ord>;

    // type PartialOrd= Unimplemented<trait_marker::PartialOrd>;

    // type Hash= Unimplemented<trait_marker::Hash>;

    // type FmtWrite= Unimplemented<trait_marker::FmtWrite>;
    
    // type IoWrite= Unimplemented<trait_marker::IoWrite>;
    
    // type IoSeek= Unimplemented<trait_marker::IoSeek>;
    
    // type IoRead= Unimplemented<trait_marker::IoRead>;

    // type IoBufRead= Unimplemented<trait_marker::IoBufRead>;
    
    // type Error= Unimplemented<trait_marker::Error>;
