Expand description
This trait let’s us visit a specific field inside a struct. similar to lens in Haskell
e.g.
Consider a scenerio where, you are passing a generic to a function and incidentally you also want
to get a value inside it. Let’s assume that there are multiple structs with the same field
foo
you might wish to for example view it. But, it would be impossible to do so,

fn set(&mut self) -> &mut Self::Inner
If we have access to &mut self
try and mutate &mut Inner
