Trait FavoriteSink 

pub trait FavoriteSink: Send + Sync {
    // Required method
    fn push_favorite<'life0, 'life1, 'async_trait>(
        &'life0 self,
        item_id: &'life1 str,
        is_favorite: bool,
    ) -> Pin<Box<dyn Future<Output = Result<(), RepoError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

The subset of the repository the drain needs.

Narrow on purpose: a test double for MediaRepository would be forty unimplemented methods, which is how a drain ends up untested.
