1、Vector// 1. Vector 可变数组 // 通过构造函数创建 let v: Vec<i32> = Vec::new(); // 通过宏创建,可以推断出类型 let v = vec![1, 2, 3]; // 更新Vector let mut v = Vec::new(); // 必须是不可变,否则报错 v.push(5); v.push(6); v.push(7); v.

没有自带split等常用操作，仅仅只有几个简单的容器操作函数，string甚至被人嘲讽就是vector<char>的别名。
分配一个空Strings字符串vector,用par_iter_mut().for_each 并行填充随机值。 尽管有多个可选方法来对可枚举的数据类型进行排序,但并行不稳定(par_sort_unstable)算法通常比稳定排序(stable sorting)算法要快。 extern crate rand; extern crate rayon; use rand::{Rng, thread_rng}; use rand::distributions:...

in PANs and Mag Stripes, but you probably shouldn't, as this will put you in PCI scope and the most common vector for POS breaches is key logging. If you use terminals for manual card entry, you'll bypass any key loggers that might be maliciously running on the point-of-sale system...
