stringslice's Issues

.slice(..0) panics!

If we have this very little Rust snippet:

fn main() {
    let s = String::from("abcd");
    println!("range `{}`", &s.as_str()[..0]);
}

We can see that if we pass the range ..0 to a &str slice, it works by returning an empty string slice.

If we do the same operation with your crate, e.g. s.slice(..0) it panics with an overflow.
Is this a bug? Shouldn't that follow the "common rules" of Rust slices ranges and returning an empty slice too?

Thank you.

UPDATE: This panic overflow happens also specifying range 0..0 which still works fine in normal &str slice.
UPDATE2: This panic overflow happens also specifying range LEN..LEN which - again - still works fine in normal &str slice.
