Trait diesel::query_builder::AsQuery

pub trait AsQuery {
    type SqlType;
    type Query: Query<SqlType = Self::SqlType>;
    fn as_query(self) -> Self::Query;
}

Types that can be converted into a complete, typed SQL query. This is used internally to automatically add the right select clause when none is specified, or to automatically add RETURNING * in certain contexts
