      # `Tapioca::Dsl::Compilers::ActiveRecordRelations` decorates RBI files for subclasses of
      # `ActiveRecord::Base` and adds
      # [relation](http://api.rubyonrails.org/classes/ActiveRecord/Relation.html),
      # [collection proxy](https://api.rubyonrails.org/classes/ActiveRecord/Associations/CollectionProxy.html),
      # [query](http://api.rubyonrails.org/classes/ActiveRecord/QueryMethods.html),
      # [spawn](http://api.rubyonrails.org/classes/ActiveRecord/SpawnMethods.html),
      # [finder](http://api.rubyonrails.org/classes/ActiveRecord/FinderMethods.html), and
      # [calculation](http://api.rubyonrails.org/classes/ActiveRecord/Calculations.html) methods.
      #
      # The compiler defines 3 (synthetic) modules and 3 (synthetic) classes to represent relations properly.
      #
      # For a given model `Model`, we generate the following classes:
      #
      # 1. A `Model::PrivateRelation` that subclasses `ActiveRecord::Relation`. This synthetic class represents
      # a relation on `Model` whose methods which return a relation always return a `Model::PrivateRelation` instance.
      #
      # 2. `Model::PrivateAssocationRelation` that subclasses `ActiveRecord::AssociationRelation`. This synthetic
      # class represents a relation on a singular association of type `Model` (e.g. `foo.model`) whose methods which
      # return a relation will always return a `Model::PrivateAssocationRelation` instance. The difference between this
      # class and the previous one is mainly that an association relation also keeps track of the resource association
      # for this relation.
      #
      # 3. `Model::PrivateCollectionProxy` that subclasses from `ActiveRecord::Associations::CollectionProxy`.
      # This synthetic class represents a relation on a plural association of type `Model` (e.g. `foo.models`)
      # whose methods which return a relation will always return a `Model::PrivateAssocationRelation` instance.
      # This class represents a collection of `Model` instances with some extra methods to `build`, `create`,
      # etc new `Model` instances in the collection.
      #
      # and the following modules:
      #
      # 1. `Model::GeneratedRelationMethods` holds all the relation methods with the return type of
      # `Model::PrivateRelation`. For example, calling `all` on the `Model` class or an instance of
      # `Model::PrivateRelation` class will always return a `Model::PrivateRelation` instance, thus the
      # signature of `all` is defined with that return type in this module.
      #
      # 2. `Model::GeneratedAssociationRelationMethods` holds all the relation methods with the return type
      # of `Model::PrivateAssociationRelation`. For example, calling `all` on an instance of
      # `Model::PrivateAssociationRelation` or an instance of `Model::PrivateCollectionProxy` class will
      # always return a `Model::PrivateAssociationRelation` instance, thus the signature of `all` is defined
      # with that return type in this module.
      #
      # 3. `Model::CommonRelationMethods` holds all the relation methods that do not depend on the type of
      # relation in their return type. For example, `find_by!` will always return the same type (a `Model`
      # instance), regardless of what kind of relation it is called on, and so belongs in this module.
      # This module is used to reduce the replication of methods between the previous two modules.
      #
      # Additionally, the actual `Model` class extends both `Model::CommonRelationMethods` and
      # `Model::PrivateRelation` modules, so that, for example, `find_by` and `all` can be chained off of the
      # `Model` class.
      #
      # **A note on find**: `find` is typed as `T.untyped` by default.
      #
      # While it is often used in the manner of `Model.find(id)`, Rails does support pasing in an array to find, which
      # would then return a `T::Enumerable[Model]`. This would force a static cast everywhere find is used to avoid type
      # errors. This is not ideal considering very few users of find use the array syntax over a where. With untyped,
      # this cast is optional and so it was decided to avoid typing it. If you need runtime guarentees when using `find`
      # the best method of doing so is by casting the return value to the model: `T.cast(Model.find(id), Model)`.
      # `find_by` does guarentee a return value of `Model`, so find can can be refactored accordingly:
      # `Model.find_by!(id: id)`. This will avoid the cast requirement at runtime.
      #
      # **CAUTION**: The generated relation classes are named `PrivateXXX` intentionally to reflect the fact
      # that they represent private subconstants of the Active Record model. As such, these types do not
      # exist at runtime, and their counterparts that do exist at runtime are marked `private_constant` anyway.
      # For that reason, these types cannot be used in user code or in `sig`s inside Ruby files, since that will
      # make the runtime checks fail.
      #
      # For example, with the following `ActiveRecord::Base` subclass:
      #
      # ~~~rb
      # class Post < ApplicationRecord
      # end
      # ~~~
      #
      # this compiler will produce the RBI file `post.rbi` with the following content:
      # ~~~rbi
      # # post.rbi
      # # typed: true
      #
      # class Post
