Clang version 5 is a good pick, GCC version +6 lags behind in terms of ``constexpr`` compilation time (At least on my +setup), but compiles correctly. Visual Studio 2017 also works correctly! + +Note that gcc 5 isn't supported. (Here's an `old compat branch`_ where a small amount of stuff was ported.) + +.. _old compat branch: https://github.com/cbeck88/frozen/tree/gcc5-support + +Usage +----- + +Compiled with ``-std=c++14`` flag: + +.. code:: C++ + + #include <frozen/set.h> + + constexpr frozen::set<int, 4> some_ints = {1,2,3,5}; + + constexpr bool letitgo = some_ints.count(8); + + extern int n; + bool letitgoooooo = some_ints.count(n); + + +As the constructor and some methods are ``constexpr``, it's also possible to write weird stuff like: + +.. code:: C++ + + #include <frozen/set.h> + + template<std::size_t N> + std::enable_if_t< frozen::set<int, 3>{{1,11,111}}.count(N), int> foo(); + +String support is built-in: + +.. code:: C++ + + #include <frozen/unordered_map.h> + #include <frozen/string.h> + + constexpr frozen::unordered_map<frozen::string, int, 2> olaf = { + {"19", 19}, + {"31", 31}, + }; + constexpr auto val = olaf.at("19"); + +The associative containers have different functionality with and without ``constexpr``. +With ``constexpr``, frozen maps have immutable keys and values. Without ``constexpr``, the +values can be updated in runtime (the keys, however, remain immutable): + +.. code:: C++ + + + #include <frozen/unordered_map.h> + #include <frozen/string.h> + + static constinit frozen::unordered_map<frozen::string, frozen::string, 2> voice = { + {"Anna", "???"}, + {"Elsa", "???"} + }; + + int main() { + voice.at("Anna") = "Kristen"; + voice.at("Elsa") = "Idina"; + } + +You may also prefer a slightly more DRY initialization syntax: + +.. code:: C++ + + #include <frozen/set.h> + + constexpr auto some_ints = frozen::make_set<int>({1,2,3,5}); + +There are similar ``make_X`` functions for all frozen containers. + +Exception Handling +------------------ + +For compatibility with STL's API, Frozen may eventually throw exceptions, as in +``frozen::map::at``. If you build your code without exception support, or +define the ``FROZEN_NO_EXCEPTIONS`` macro variable, they will be turned into an +``std::abort``. + +Extending +--------- + +Just like the regular C++14 container, you can specialize the hash function, +the key equality comparator for ``unordered_*`` containers, and the comparison +functions for the ordered version. + +It's also possible to specialize the ``frozen::elsa`` structure used for +hashing. Note that unlike `std::hash`, the hasher also takes a seed in addition +to the value being hashed. + +.. code:: C++ + + template <class T> struct elsa { + // in case of collisions, different seeds are tried + constexpr std::size_t operator()(T const &value, std::size_t seed) const; + }; + +Ideally, the hash function should have nice statistical properties like *pairwise-independence*: + +If ``x`` and ``y`` are different values, the chance that ``elsa<T>{}(x, seed) == elsa<T>{}(y, seed)`` +should be very low for a random value of ``seed``. + +Note that frozen always ultimately produces a perfect hash function, and you will always have ``O(1)`` +lookup with frozen. It's just that if the input hasher performs poorly, the search will take longer and +your project will take longer to compile. + +Troubleshooting +--------------- + +If you hit a message like this: + +.. code:: none + + [...] + note: constexpr evaluation hit maximum step limit; possible infinite loop? + +Then either you've got a very big container and you should increase Clang's +thresholds, using ``-fconstexpr-steps=1000000000`` for instance, or the hash +functions used by frozen do not suit your data, and you should change them, as +in the following: + +.. code:: c++ + + struct olaf { + constexpr std::size_t operator()(frozen::string const &value, std::size_t seed) const { return seed ^ value[0];} + }; + + constexpr frozen::unordered_set<frozen::string, 2, olaf/*custom hash*/> hans = { "a", "b" }; + +Tests and Benchmarks +-------------------- + +Using hand-written Makefiles crafted with love and care: + +.. code:: sh + + > # running tests + > make -C tests check + > # running
