- //! Returns the union of two sets.
- //! @relates hana::set
- //!
- //! Given two sets `xs` and `ys`, `union_(xs, ys)` is a new set containing
- //! all the elements of `xs` and all the elements of `ys`, without
- //! duplicates. For any object `x`, the following holds:
- //! @code
- //! x ^in^ union_(xs, ys) if and only if x ^in^ xs || x ^in^ ys
- //! @endcode
- //!
- //!
- //! @param xs, ys
- //! Two sets to compute the union of.
- //!
- //!
- //! Example
- //! -------
- //! @include example/union.cpp
