FFI - Creating a "&[u8]" from "const char*" Slice

Sure, a String (or str ) is designed to only contain UTF-8 bytes, but there is no requirement to crash the program when you try to convert non-UTF-8 bytes to a String.

That's a decision the developer explicitly made when they used unwrap() instead of handling the error gracefully (e.g. by reporting to the user that the data they entered was invalid).

you might want to look at my former discussion to get an idea what it involves not to do just EXIT and out as it is common practice
Proper UTF-8 Error Handling
The Example Use Case also shows why it is a real Requirement in Real World.
