Defined in adapters.hpp.
This type should be a stateless trivially default constructible with a call operator of signature bool operator()(Value const&, Value const&) (possibly noexcept, inline and/or constexpr also) for use with, for example, std::unordered_map.
| Value | the type of objects to compare. |
The second template parameter exists for SFINAE.
