Find substring t consisting in characters i (included) to j (excluded) of string s. Character indices start at 0 unless specified otherwise. Make sure that multibyte characters are properly handled. 查找由字符串s的字符I(包括)到j(不包括)组成的子字符串t。 除非另有说明,字符索引从0开始。 确保...
String find. Part 1We use find() and get an option—this helps us determine if a value exists or not. To get the actual value, we use if let Some. if Part 2After we call find() successfully we can use get() to take a substring at the index returned. ...
