slicestring is a crate for slicing Strings.
It provides the slice() method for String and &str.
It takes a std::ops::Range as an argument.
It slices the String or &str and returns the sliced one as a String.
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.
use slicestring::Slice;
let mut s = String::from("hello 😃");
s = s.slice(5..);
assert_eq!("😃", s);
