| constexpr auto | boost::hana::contains |
Returns whether the key occurs in the structure.Given a Searchable structure xs and a key, contains returns whether any of the keys of the structure is equal to the given key. If the structure is not finite, an equal key has to appear at a finite position in the structure for this method to finish. For convenience, contains can also be applied in infix notation.

| constexpr auto | boost::hana::in = hana::infix(hana::flip(hana::contains)) |
Return whether the key occurs in the structure.Specifically, this is equivalent to contains, except in takes its arguments in reverse order. Like contains, in can also be applied in infix notation for increased expressiveness. This function is not a method that can be overriden; it is just a convenience function provided with the concept.
