Rust 的严谨性避免了像 C/C++中的数组到指针的衰变问题: //C++ code#include <iostream>usingnamespacestd;//Looks can be deceiving: arr is not a pointer//to an array of 5 integers. It has decayed to//a pointer to an integer.voidprint_array_size(int(*arr)[5]){//prints 8 (the size o...
Let’s talk about an array in Rust. In Rust, an array refers to a fixed-size collection of elements of the same type. Unlike vector, an array has a fixed length which is determined at compile time and which cannot be changed at runtime. In addition, arrays are stack-allocated which m...
In Rust, a vector (Vec<T>) is a dynamic array that allows you to store a collection of elements of the same type. Unlike arrays, vectors can grow or shrink in size. They are part of Rust's standard library and provide a flexible and powerful way to work with collections. Vectors are...
To actually create a vector, we use a concrete type like <vector>u32, a vector of type u32, or <vector>String, a vector of type String.A common way to declare and initialize a vector is with the vec! macro. This macro also accepts the same syntax as the array constructor.Rust ...

在Rust中,可以使用as_bytes()方法将字符串转换为字节数组,然后使用to_vec()方法将字节数组转换为向量(Vector)。 以下是一个示例代码: 代码语言:txt 复制 fn main() { let s = String::from("Hello, world!"); let bytes = s.as_bytes(); let vector = bytes.to_vec(); println!("{:?}", vecto...
