R3 is a reactive extensions library and asynchronous data pipeline framework. It provides a system for composing asynchronous data streams, managing reactive state, and coordinating event sequences using observable patterns.
The project distinguishes itself with a deterministic testing toolkit that mocks time and frame updates to ensure reproducible unit tests for asynchronous logic. It also includes observability tools for tracking active subscriptions and generating stack traces to identify memory leaks, alongside centralized exception routing for pipeline recovery.
The framework covers a broad surface of reactive capabilities, including stream composition, pipeline transformations, and thread-aware scheduling. It provides utilities to convert standard events, property changes, and game engine signals into unified reactive streams, and includes data binding logic to link reactive properties to command execution.
