RustStrings are UTF-8. To get random access, you'll have to convert them to.bytes()or.chars(). And if you're reading aStringmade entirely of 0s and 1s? Convert them tobools as follows: lets:String=scan.next();letv:Vec<bool>=s.chars().map(|ch|ch==‘1’).collect(); ...
Rust doesn't represent paths as Strings, so we need to convert the Path returned from Path::parent. This code chooses to do this lossily, replacing characters it doesn't recognize with � 109. Number of bytes of a type Set n to the number of bytes of a variable t (of type T)....
