Use thesplit_whitespace()Method in Rust Thesplit_whitespace()is used to split the input string into different strings. Since it returns the iterator, we can iterate it through the token. Example Code: fnmain(){letwords="Rust is a programming language".to_string();letmuti=1;fortokeninwords...

s.split_whitespace() 以换行分割. s.lines() 以正则表达式分割.2 Regex::new(r"\s")?.split("one two three") 1 会产生内存分配. 如果 x 已经是 String 的情况下可能不是性能的最优解. 2 依赖regex crate. I/O 用途代码 创建新文件 File::create(PATH)? 同上, 但给出选项 OpenOptions::new(...
