由于Rust有多种数据排布风格(默认的Rust风格,还有C语言风格,primitive和transparent风格),在Rust风格中,Rust可以对元组中的元素做任意重排,也包括padding的位置,因而图中的排列只是一种可能,也许i32和char的位置在Rust中会进行互换,Rust是根据其优化算法做出其认为最优的排序,对最终排序结果并没有统一规则。 上图为该t...

的方法是将每个u8元素转换为对应的字符,并将所有字符放入一个新的Vec<char>中。 以下是一个示例代码: 代码语言:rust 复制 fnmain(){letbytes:Vec<u8>=vec![97,98,99,100];// 示例的字节向量letchars:Vec<char>=bytes.iter().flat_map(|&byte|char::from(byte).to_lowercase()).collect();println!
在编程中，有时我们需要将数字转换为字母，例如将数字表示的年份转换为对应的字母表示，或者将数字编码...
