(2) | (since C++23) (exposition only*) |
1) A type T models and satisfies the concept tuple-like if std::remove_cvref_t<T> is a specialization of
- std::array,
|
(since C++26) |
- std::pair,
- std::tuple, or
- std::ranges::subrange.
2) pair-like objects are tuple-like objects with exactly 2 elements.
Notes
tuple-like types implement the tuple protocol, i.e., such types can be used with std::get, std::tuple_element and std::tuple_size.
Elements of tuple-like types can be bound with structured binding.
