Derive macros are created to derive a trait on structs. Lets create a trait called Serialize and Deserialize that supports two functions -

use std::fmt::Error;

trait Serialize {
	fn serialize(&self) -> Vec<u8>;
}

trait Deserialize: Sized {
	fn deserialize(base: &[u8]) -> Result<Self, Error>;
}

We need to create two Custom derive macros for these traits. Both should be able to pack a struct into bytes and vice versa.

What is the problem in this approach? Does it work for any struct? or just for this specific struct?

How can we make it more generic
