No hash function is perfect, but some are useful. wyhash and wyrand are the ideal 64-bit hash function and PRNG respectively: solid: wyhash passed SMHasher, wyrand passed BigCrush, practrand. portable: 64-bit/32-bit system, big/little endian. ...
Boost说明了hash用于STL容器,而不是其它。 This hash function is designed to be used in containers based on the STL and is not suitable as a general purpose hash function. VS2015会使用 FNV-1a size_t operator()(const argument_type& _Keyval) const { // hash _Keyval to size_t value by ps...

针对您提供的错误信息“in function 'std::size_t boost::hash_value(const std::error_code&)': /usr/in”,我们可以从以下几个方面进行分析和解答: 1. 错误信息分析 错误信息表明在尝试调用boost::hash_value(const std::error_code&)函数时出现了问题。这个函数通常用于计算std::error_code对象的哈希...
