尽管如此,如果没有特定要求(哈希 DoS 攻击的风险),tsl::hopscotch_map和tsl::hopscotch_set在大多数情况下应该足够了,并且应该是你的默认选择,因为它们通常表现更好。 与std::unordered_map差异 tsl::hopscotch_map 尝试拥有与 std::unordered_map 类似的接口,但存在一些差异。 插入时迭代器失效的行为方式不同。

In Visual C++ .NET 2003, members of the <hash_map> and <hash_set> header files are no longer in the std namespace, but rather have been moved into the stdext namespace. See The stdext Namespace for more information. Example 複製 // hash_set_value_comp.cpp // compile with: /EHs...
