`clippy::indexing_slicing` does not report slicing on &str

[link2xt]

Summary

indexing_slicing does not report slicing of &str and it breaks.

Lint Name

clippy::indexing_slicing

Reproducer

I tried this code:

#![warn(clippy::indexing_slicing)]

fn main() {
    let s = "foobar";
    let _ = s[..500];
    println!("Hello, world!");
}

I expected clippy to report a warning, but it does not. The code crashes when I run it:

$ cargo run

    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.10s

[y21]

This is covered by the string_slice lint. If you change the reproducer to use #![warn(clippy::string_slice)] then you should get a warning.

Then this can be treated as documentation issue, indexing_slicing docs should mention string_slice.
