Classes
struct	fe::StrHash
	Hashes the characters of a string; transparent, so std::string keys may be looked up by std::string_view. More...

Namespaces
namespace	fe

Typedefs
StrMap/StrSet
Keyed by std::string but also looked up by std::string_view or const char* without building a std::string.
template<class V>
using	fe::StrMap = ankerl::unordered_dense::map<std::string, V, StrHash, std::equal_to<>>
using	fe::StrSet = ankerl::unordered_dense::set<std::string, StrHash, std::equal_to<>>

Functions
template<std::integral T>
constexpr size_t	fe::hash_combine (size_t seed, T v) noexcept
	Folds v into seed like ankerl::unordered_dense hashes a tuple: one 128-bit multiply, halves xored.
