swap function order for better read flow

I was reading this error message for the first time.

I was a little bit confused when reading that part:
```
foo.bar(); // we can now use this method since i32 implements the Foo trait
```

At the time I was reading `// we can now use this method` I wasn't sure why. It only made sense when reading on. So swapping these parts results in a better read flow.
