| 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 `std::slice::SliceIndex<[{integer}]>` is not implemented for `i32` | |
| = note: required because of the requirements on the impl of `std::ops::Index<i32>` for `std::vec::Vec<{integer}>` | |
| error: aborting due to previous error | |
