Derive macros are a godsend. There's macros to automatically implement serialization as well. Basically a Trait that can automatically be implemented when derived

i've only read about rust, but is there a way to influence those automatic implementations?

equality for example could be that somethings literally point to the same thing in memory, or it could be that two structs have only values that are equal to each other

Not for the built-in Eq derive macro. But you can write your own derive macros that do allow you to take options, yeah.
