Filesystem has a dependency on
in order to supply this: inline std::size_t hash_value(const path& x) { # ifdef BOOST_WINDOWS_API std::size_t seed = 0; for(const path::value_type* it = x.c_str(); *it; ++it) hash_combine(seed, *it == '/' ? L'\\' : *it); return seed; # else // BOOST_POSIX_API return hash_range(x.native().begin(), x.native().end()); # endif }
The problem with this is that functional is a heavy-weight dependency for such relatively minor feature.
See http://www.pdimov.com/tmp/report-develop-3b5a9f4/module-weights.html
Is there any recommended way to avoid the functional dependency?
A good question. For the same reason I am reluctant to implement hash support in Boost.Optional. Regards, Andrzej
