Flexible trait function parameter names in Rust

When we define a trait we give it a function statement of the form fn blah(foo: Bar). But when implementing this trait the parameter name (here it is foo) can be changed as you wish. So let's have an example.

Playground

/// A very simple struct
struct Simple;
/// A struct that doesn't matter
struct Whatever;

/// A trait that does something _very_ complex
trait SuperDuperComplexThing {
    fn do_super_duper_complex_thing(some_extremely_and_needlessly_long_parameter: Whatever) -> Whatever ;
}

impl SuperDuperComplexThing for Simple {
    fn do_super_duper_complex_thing(simple_param: Whatever) -> Whatever {
        Whatever
    }
}

And this works perfectly. It compiles.

What is the difference between parsing and serialization?

So, I've come across both terms and I don't understand how serialization is different than parsing. They seem to be different as I've never read about both in the same context but they seem to be similar as they do roughly the same thing, I think.
