但是，正如注释说的，这里直接使用了 medium strings 的存储方式。比如 folly/io/IOBuf.cpp 中的调用：...

在FBStringBenchmark.cpp中。 主要类 ::folly::fbstring str("abc")中的 fbstring 为 basic_fbstring的别名 :typedef basic_fbstring<char> fbstring; basicfbstring 在 fbstring_core 提供的接口之上,实现了 std::string 定义的所有接口。里面有一个私有变量 store,默认值即为 fbstring_core。basic_fbstring 的定义...

如何在Dev-Cpp中使用C++11中的函数:stoi、to_string、unordered_map、unordered_set、auto,程序员大本营,技术文章内容聚合第一站。
一、string头文件 主要包含一些字符串转换的函数 // sto* NARROW CONVERSIONS // sto* WIDE CONVERSIONS stoi //convert string to int stol //convert string to long stoul //convert string to unsigned long stoll //convert string to long long ...
