//! The `extern "C++"` bridge for the generic Tuple intersection shim.
//!
//! Nothing here mentions `RustSummary`, so like the union bridge this gets its
//! own file and aliases the two sketch shim types from [`crate::tuple_generic`]
//! the ordinary `extern "C++"` way.
//!
//! `get_result` is declared `Result<..>` because upstream throws when it is
//! called before any `update`: that state is the infinite "universe", not an
//! empty result.
