Then our code programmatically set the new element value.

This function won't work and the result will be undefined if your vector is not sorted.TODO .dedup A linked list is more suitable than a vector when items are likely to be inserted or removed from either end or from points within the list. It takes a base value, and then calls a closure to accumulate the value upon the result of the last value.These mostly correspond to what you may be used to on the std::string class and in boost string algorithms.Most find / match / trim / split string operations in Rust are efficient because they neither modify the existing string, nor return a duplicate to you. a pointer and a length into your existing string to denote the range that is the result.In other words it is not duplicating the string, nor is it modifying the existing string.

Instead it is just telling you what the trimmed range is within the &str you're already looking at.So Also be aware that trim_left() and and trim_right() above are affected by the directionality of the string.Most strings read from left-to-right, but strings in Arabic or Hebrew are read right-to-left and will start with a control character that sets their base direction right-to-left.Some locales will use dots or commas for separators.Some languages will use dots or commas for the decimal place.Note one immediate advantage of Rust is it uses string slices.
