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 the sliced one as a String.

Examples:

``` 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); ```

You can also use a negative value for the second index.

``` use slicestring::Slice;

let mut s = String::from("hello"); s = s.slice(..-3); assert_eq!("he", s); ```

or

``` use slicestring::Slice;

let mut s = String::from("hello"); s = s.slice(1..-1); assert_eq!("ell", s); ```
