Crate slicestring 

slicestring is a crate for slicing Strings. It provides the slice() method for String and &str. It takes the index-range as an argument, whereby also a negative value can be passed for the second index. It slices the String or &str and returns a the sliced one as a String.

Example:

use slicestring::Slice;
 
let mut s = "hello world!";
s = s.slice(..5);
assert_eq!("hello", s);

It also works with emoticons since the slice() method takes into account characters.

let mut s = String::from("hello 😃");
s = s.slice(5..);
assert_eq!("😃", s);
