The issue was that the trait `FromHex` has changed and is now using `FromIterator<u8>` instead of `FromIterator<Vec<u8>>` and was `inferred` to `[u8]` instead of `Vec<u8>`. Thus, has not compile-time size and won't work! Well, this could be improved to be stack allocated because we know the `size` of the hexstring but in this case I think is sufficient and only used in tests! |
