I'm really new to Rust, this is the first thing I've ever actually pushed to github in a rust project, so please double check that it's correct. I noticed that the in-doc example for the string's get() function was referring to get_mut(). Looks like a copy/paste issue.
```rust
fn main() {
let v = String::from("🗻∈🌏");
assert_eq!(Some("🗻"), v.get(0..4));
// indices not on UTF-8 sequence boundaries
assert!(v.get(1..).is_none());
assert!(v.get(..8).is_none());
// out of bounds
assert!(v.get(..42).is_none());
}
```
results in:
```
jhford-work:~/rust/redish $ cat get-example.rs
fn main() {
let v = String::from("🗻∈🌏");
assert_eq!(Some("🗻"), v.get(0..4));
// indices not on UTF-8 sequence boundaries
assert!(v.get(1..).is_none());
assert!(v.get(..8).is_none());
// out of bounds
assert!(v.get(..42).is_none());
}
jhford-work:~/rust/redish $ rustc get-example.rs
jhford-work:~/rust/redish $ ./get-example ; echo $?
0
```
I did not build an entire rust toolchain as I'm not totally sure how to do that.
