 When writing tests in Rust, you'll probably use `assert_eq!(a, b)` _a lot_.
 
-If such a test fails, it will present all the details of `a` and `b`, but you have to spot, the differences yourself, which is not always straightforward, like here:

 * The replacement is only effective in your own crate, not in other libraries
   you include.
 * `assert_ne` is also switched to multi-line presentation, but does _not_ show
