21-22: Semantic improvement in naming the disposable strategy.

The renaming from expected_disposable_strategy to optimal_disposable_strategy is a good change. It more accurately conveys that this strategy is considered the best or most efficient for the given context, rather than just an expected one. This semantic shift provides better clarity to developers using this code.

Let's verify if there are any remaining uses of the old name in the codebase:

src/rpp/rpp/sources/never.hpp (2)

21-22: Improved disposable strategy for never observable

The changes to the never_strategy struct are well-considered and align with the behavior of the never observable:

1. Renaming expected_disposable_strategy to optimal_disposable_strategy improves clarity.
2. Changing the type to fixed_disposable_strategy<0> optimizes the disposable management for an observable that never emits or terminates.

These modifications likely result in more efficient resource management for the never observable.

---

21-22: Verify impact of changes on never() function

The changes to never_strategy are well-contained and don't affect the public API or the behavior of the never() function. However, it's important to ensure that these changes don't have unintended consequences elsewhere in the codebase.

Let's verify the usage of never_strategy and never():

✅ Verification successful

Changes are localized and do not affect the public API

The modifications to never_strategy are confined to never.hpp and do not impact the public API or the behavior of the never() function in other parts of the codebase.

src/rpp/rpp/operators/distinct.hpp (3)

26-26: Approved: Improved representation of disposable strategy

The change from a member variable to a static constant preferred_disposable_mode is a good improvement. It clearly defines the disposable behavior at compile-time, which can lead to better optimizations. The use of disposable_mode::None suggests that this observer strategy doesn't require any specific disposable behavior, which simplifies the implementation.

---

Line range hint 1-90: Summary: Refactoring of disposable strategy representation

The changes in this file are part of a broader refactoring effort focused on improving the representation and naming of disposable strategies. The core functionality of the distinct operator remains unchanged, but the way disposable strategies are defined and named has been updated. These changes should lead to more clear and consistent code across the library.

src/rpp/rpp/operators/details/forwarding_subject.hpp (3)

29-29: Update to preferred_disposable_mode aligns with the new disposable handling

Changing from using preferred_disposable_strategy to static constexpr auto preferred_disposable_mode and assigning it rpp::details::observers::disposable_mode::None improves clarity by explicitly specifying the disposable mode as a constant value rather than a type alias.

---

45-45: Renaming to optimal_disposable_strategy enhances semantic clarity

The renaming of expected_disposable_strategy to optimal_disposable_strategy more accurately reflects the purpose of the type alias, indicating that it represents the most suitable disposable strategy deduced for the subject state.

---

59-59: Ensure consistency with the updated disposable strategy naming

In the get_observable method, the use of optimal_disposable_strategy replaces the previous expected_disposable_strategy. Verify that all references to expected_disposable_strategy in the codebase have been updated to maintain consistency and prevent potential compilation errors.

src/rpp/rpp/observables/details/chain_strategy.hpp (4)

27-27: Update static_assert to use optimal_disposable_strategy

The change to use optimal_disposable_strategy in the static assertion aligns with the updated disposable strategy approach, ensuring that the operator chain meets the necessary constraints with the optimal strategy.

---

30-31: Define optimal_disposable_strategy and value_type appropriately

Defining optimal_disposable_strategy using TStrategy::template updated_optimal_disposable_strategy<typename base::optimal_disposable_strategy> correctly propagates the optimal strategy through the chain. The value_type definition aligns with the result type from operator_traits, ensuring type consistency.

---

50-51: Update subscription logic to utilize optimal_disposable_strategy

The modifications in the subscribe method to use optimal_disposable_strategy in the conditional checks and in the call to lift_with_disposable_strategy reflect the new disposable strategy handling appropriately. This ensures that the optimal strategy is considered during subscription.

---

76-77: Consistent use of optimal_disposable_strategy in single-strategy chain

In the specialization of the chain class for a single strategy, defining optimal_disposable_strategy using deduce_optimal_disposable_strategy_t<TStrategy> ensures consistency with the multi-strategy case and properly deduces the optimal strategy for the single operator.

src/rpp/rpp/observers/lambda_observer.hpp (2)

25-26: Addition of preferred_disposable_mode enhances disposal management

The introduction of static constexpr auto preferred_disposable_mode = rpp::details::observers::disposable_mode::Auto; in the lambda_strategy struct effectively sets the preferred disposal mode to Auto. This improves resource management by indicating a preference for automatic disposal behavior within the observer pattern.

---

src/rpp/rpp/observables/fwd.hpp (2)

114-116: Ensure operators comply with updated operator_chain concept

The updated operator_chain concept introduces typename std::decay_t<Op>::template updated_optimal_disposable_strategy<...> and requires it to satisfy disposable_strategy. This change might affect existing operators that do not define updated_optimal_disposable_strategy. Please verify that all operator implementations adhere to the new requirements.

Run the following script to identify operators missing updated_optimal_disposable_strategy:

#!/bin/bash
# Description: Find operator classes that may lack `updated_optimal_disposable_strategy`.

# Search for operator classes that define `operator_traits` but do not define `updated_optimal_disposable_strategy`.
ast-grep --lang cpp --pattern $'class $_ {
  $$$
  template <typename> struct operator_traits { $$$ };
  $$$
}' --json | jq -r '.[] | select(.code | test("updated_optimal_disposable_strategy") | not) | .file' | sort -u

---

25-28: Verify compatibility of observable_strategy with existing strategies

The addition of typename S::optimal_disposable_strategy and the constraint that it satisfies disposable_strategy may introduce breaking changes for existing strategies that do not define optimal_disposable_strategy.
