📝 Walkthrough
📝 Walkthrough ## Walkthrough The pull request introduces significant changes to the `concat.hpp` and `switch_on_next.hpp` files within the ReactivePlusPlus library. In `concat.hpp`, the `concat_disposable` class now inherits from `rpp::details::base_disposable`, altering its resource management approach. The method `composite_dispose_impl` has been renamed to `base_dispose_impl`. In `switch_on_next.hpp`, the `switch_on_next_state_t` class also shifts to inherit from `base_disposable`, introducing new methods for managing disposables and modifying existing methods to align with the new structure. ## Changes | File Path | Change Summary | |----------------------------------------------|-------------------------------------------------------------------------------------------------------| | src/rpp/rpp/operators/concat.hpp | - `concat_disposable` now inherits from `rpp::details::base_disposable` instead of `rpp::composite_disposable`.
- Renamed `composite_dispose_impl` to `base_dispose_impl`.
- Added header ``. | | src/rpp/rpp/operators/switch_on_next.hpp | - `switch_on_next_state_t` now inherits from `rpp::details::base_disposable` instead of `refcount_disposable`.
- Added methods: `get_base_child_disposable()` and `get_inner_child_disposable()`.
- Updated `base_dispose_impl` to manage disposables correctly. | | src/tests/rpp/test_switch_on_next.cpp | - Added a new test case for `switch_on_next` operator focusing on completion behavior.
- Included header `rpp_trompeloil.hpp` for mocking framework. | ## Possibly related PRs - #640: Modifies the `concat.hpp` file, enhancing the `concat_state_t` class's memory management, closely related to changes in `concat_disposable`. - #644: Involves changes to `concat.hpp`, specifically in error handling logic, which may interact with the new disposal mechanisms. - #677: Refactors the `concat_disposable` class, directly impacting the same class modified in the main PR. - #661: Addresses modifications in the `base_disposable` class, relevant to the inheritance structure changes in `concat_disposable`. - #679: Updates documentation regarding disposables, providing context for changes made in the `concat_disposable` class. > 🐇 In the code's burrow, changes abound, > With disposables shifting, new structures are found. > From `composite` to `base`, a leap we embrace, > Managing resources with newfound grace. > So hop along, dear coder, let’s celebrate, > For in this code garden, we cultivate! 🌼

🪧 Tips ### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit , please review it.` - `Generate unit testing code for this file.` - `Open a follow-up GitHub issue for this discussion.` - Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples: - `@coderabbitai generate unit testing code for this file.` - `@coderabbitai modularize this function.` - PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples: - `@coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.` - `@coderabbitai read src/utils.ts and generate unit testing code.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.` - `@coderabbitai help me debug CodeRabbit configuration file.` Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments. ### CodeRabbit Commands (Invoked using PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai full review` to do a full review from scratch and review all the files again. - `@coderabbitai summary` to regenerate the summary of the PR. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository. - `@coderabbitai help` to get help. ### Other keywords and placeholders - Add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. - Add `@coderabbitai summary` to generate the high-level summary at a specific location in the PR description. - Add `@coderabbitai` anywhere in the PR title to generate the title automatically. ### CodeRabbit Configuration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information. - If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json` ### Documentation and Community - Visit our [Documentation](https://docs.coderabbit.ai) for detailed information on how to use CodeRabbit. - Join our [Discord Community](http://discord.gg/coderabbit) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.
