Rust 程序设计语言 简体中文版 1.85.0猜数字程序的第一部分请求和处理用户输入,并检查输入是否符合预期的格式。首先,我们会 允许玩家输入一个猜测。在 src/main.rs 中输入示例 2-1 中的代码。 文件名:src/main.rs use std::io; fn main() { println!("Guess the number!"); println!("Please input your guess."); 输入/输出库引入当前作用域。io 库来自于标准库,也被称为 std: use std::io; 默认情况下,Rust 设定了若干个会自动导入到每个程序作用域中的标准库内容,这组内容被 称为 预导入(prelude) 内容。你可以在标准库文档中查看预导入的所有内容。 如果你需要的类型不在预导入内容中,就必须使用 use 语句显式地将其引入作用域。std::io 库提供很多有用的功能,包括接收用户输入的功能。 回忆一下,我们在程序的第一行使用 use std::io; 从标准库中引入了输入/输出功能。现在调 用 io 库中的函数 stdin,这允许我们处理用户输入: io::stdin() .read_line(&mut guess) 如果程序的开头没有使用 use std::io; 引入 io 库,我们仍可以通过把函数调用写成 std::io::stdin 来使用该函数。stdin0 码力 | 562 页 | 3.23 MB | 24 天前3
