Constrain Struct Generic Field in Rust
It is a quite common need to constrain struct generic field to certain types in Rust. We usually have two different ways to implement this. Trait or dispatching each of them by ourselves.

有时非常需要测量函数的执行时间。在其他语言中很容易实现比如像 Python 与 Golang,而在 Rust 实现即相对比较困难。
Measuring function time is quite necessary sometimes. It is easy to implement this in other languages but not in Rust. Therefore, this post will demonstrate some tricks to measure the function execution time.
SQL 盲注类型可以通过 sqlmap 简单地完成,亦可自己写一个简单的盲注脚本。现有的盲注脚本代码与文章质量良莠不齐,且大部分用的是线性搜索,效率奇低。
在某一个信息流网站上,看到一个 challenge,里面有部分是编程题。在 Leetcode 上有类似的题目,比如 Leetcode-282, 其要求也同样是给数字填补运算符。
