第三届中国 Rust 开发者大会 Use Rust to Develop the Decentralized Open Data Application Mike Tang daogangtang@gmail.com @daogangtang 2023-06-08 ➔ 裁员 ➔ 互联网格局定型 ➔ 平台倒闭，数据丢失 这是一个什么时代？ 互联网的终局 创业 -> 种子 dataset, data will increase quickly on any dimension. ➔ Multiple dimensions Dataset Models ➔ What is open data? Build an internet platform, but open its data to everyone. ➔ Why we need open data? The The business of the closed data model has been at the end. A New Proposal: Open Data Application The Road to Open Web ➔ From the user side, it looks like just the traditional Internet app ➔ But everyone

void g() const &; void h() &&;  Those can be rewritten as: void f(this Data&); void g(this const Data&); void h(this Data&&);9 Explicit Object Parameters  Classes often have const and non-const accessing multidimensional data:  Function call: data(x, y, z)  Multiple levels of array indexing: data[x][y][z]  C++23  Multidimensional subscript operator: data[x, y, z]  E.g.: T& operator[](size_t corresponding to std::size_t22 Literal Suffix for size_t  Use case: std::vector data{ 11, 22, 33 }; for (auto i = 0, count = data.size(); i < count; ++i) { /* ... */ }  Doesn’t compile: i is deduced as int

• cmake -B build -DQt5_DIR=”/opt/Qt5.12.1/lib/cmake/Qt5” • (2) 全局启用。修改你的 ~/.bashrc 文件添加环境变量： • export Qt5_DIR=”/opt/Qt5.12.1/lib/cmake/Qt5” ，然后重启终端。这样以后你每次构建任何 项目， find_package 都能自动找到这个路径的 Qt5 包了。

int for each? While you could just represent these values with unsigned ints or the underlying data, these new calendrical types also provide valuable abstraction.
