| error[E0277]: the type `[{integer}]` cannot be indexed by `i32` |
| --> $DIR/index-help.rs:3:5 |
| | |
| LL | x[0i32]; |
| | ^^^^^^^ slice indices are of type `usize` or ranges of `usize` |
| | |
| = help: the trait `SliceIndex<[{integer}]>` is not implemented for `i32` |
| = help: the trait `SliceIndex<[T]>` is implemented for `usize` |
| = note: required because of the requirements on the impl of `Index<i32>` for `Vec<{integer}>` |

| error: aborting due to previous error |
