A Rust library providing Monad, MonadIO, coroutines, actors, and functional programming utilities inspired by Rx, Haskell, and Python.
fpRust is a Rust library that implements functional programming constructs and concurrency models, including Monads, coroutines, actors, and reactive streams. It solves the challenge of writing expressive, composable, and asynchronous code in Rust by providing abstractions inspired by languages like Haskell, Python, and Java.
Rust developers seeking to apply functional programming patterns, build reactive systems, or implement actor-based concurrency in their applications.
Developers choose fpRust for its comprehensive set of FP utilities and concurrency abstractions in a single library, offering idiomatic Rust implementations of patterns from multiple language ecosystems.
Monad/MonadIO, Handler, Coroutine/doNotation, Functional Programming features for Rust
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides monads, do-notation, and FP macros like compose and pipe, enabling expressive, Haskell-like code as shown in the examples for data transformations.
Integrates actors, coroutines, and reactive streams (MonadIO) in one library, offering multiple paradigms inspired by Haskell, Python, and Java for flexible concurrent programming.
Supports Rust's Future trait via features like 'for_futures', allowing MonadIO and other constructs to integrate with async/await ecosystems, though with additional setup.
Borrows concepts from Haskell (do-notation), Python (coroutines), and Java (concurrency primitives), making it accessible for developers with those backgrounds.
Examples involve complex setups with mutexes, Arc clones, and handlers (e.g., HandlerThread), increasing boilerplate and potential for errors compared to native Rust patterns.
Abstractions like monads and actor systems add layers that may not be optimal for performance-critical applications where Rust's low-level control is a key advantage.
As a niche library, it might not seamlessly work with mainstream Rust async runtimes like Tokio, requiring extra glue code and offering less community support.
The README lists pattern matching as crossed out, indicating missing or planned functionality that could limit usability for advanced FP patterns.
