rust unwrap error

Comment

error.unwrap() is dangerous, it will crash your app, to be safe,
for almost all result or option enum, you should use this syntax

```
let myError: Result<String, Box<dyn error::Error>> = someResultReturningFunction();

if let Err(x) = myError {
	// Handle your error here
} else {
   // now you can unwrap it, since you are sure its not an error
}
```
