再比如使用正则表达式来替换字符串中的所有匹配项: let re = Regex::new(r"(\d{4})-(\d{2})-(\d{2})").unwrap();let date_replaced = re.replace_all("Today's date is 2022-01-01", "$2/$3/$1"); 这个正则表达式匹配日期格式“YYYY-MM-DD”,然后使用捕获组来重新排列日期格式为“MM/DD...
letcow1 = Cow::Borrowed(s);assert_eq!(cow1.into_owned(),String::from(s));// 在一个`Cow::Owned`上调用into_owned不会发生克隆操作。letcow2: Cow<str> = Cow::Owned(String::from(s));assert_eq!(cow2.into_owned(),String::from(s));...
The image tag starts with @, for example, {{@logo}} will look for the value with the key of logo in the data model, and then replace the tag with the image. The data corresponding to the image tag can be a simple URL or Path string, or a structure containing the width and height...

Replace all occurrences of the string ruru with rutie in your program. And if you would like to use ruby-sys code from Rutie rather than requiring ruby-sys you can change all existing references to ruby_sys to rutie::rubysys. 0.1 You will have additional considerations to change like ...
