How do you structure your models save/load code? (lemmy.pe1uca.dev)

I have in mind two options:

  • Code in the class being saved/loaded. The flows for each entity/model are in the same place, so it's easy to just have one file open to see all the functionalities of that class, but this means having more code in a single file.
  • Code in a dedicated class (like a factory)
    This makes each file smaller, but spreads flows of a single model into different parts of the repo, also because I'm thinking of having a directory /src/models and another like /src/export (or serialize)

What do you guys think?
What's your preferred way to organize the save and load flows?

First option for small codebases. Second option when you know your codebase will grow large enough to break things apart into multiple packages.

The thing is, you typically need dependencies for de-/serialization. You only want those dependencies in the parts of the codebase that actually do the de-/serializing. And your model will likely be included in pretty much everything in your codebase, so the de-/serializing code should not be in there.
Well, unless your programming language of choice supports feature flags with which the de-/serializing code + dependencies can be excluded from compilation, then you can think about putting it into the model package behind a feature flag.
