error[E0277]: the type `[{integer}]` cannot be indexed by `u8`
|
|
--> $DIR/indexing-requires-a-uint.rs:6:5
|
|
|
|
|
LL | [0][0u8];
|
|
| ^^^^^^^^ slice indices are of type `usize` or ranges of `usize`
|
|
|
|
|
= help: the trait `SliceIndex<[{integer}]>` is not implemented for `u8`
|
|
= note: required because of the requirements on the impl of `Index<u8>` for `[{integer}]`

help: you can convert a `usize` to an `isize` and panic if the converted value doesn't fit

LL | bar::<isize>(i.try_into().unwrap()); // i should not be re-coerced back to an isize
