Macro compose_interfaces 

macro_rules! compose_interfaces {
    (
        mod: $mod_name:ident,
        interfaces: [
            $(
                $($segment:ident)::+$(,)?
            )*
        ]
    ) => { ... };
}

Macro to combine multiple interfaces into a single composite interface.

Produces the same module structure as the interface! macro. This does NOT include the Client trait, it is still necessary to pull individual Client traits.

Example

compose_interfaces! {
     mod: composite,
     interfaces: [
         basic,
         two,
         ops,
     ]
}
