Question 1

How to use fpRust with Tokio in Rust?

Accepted Answer

Enable the 'for_futures' feature to convert fpRust constructs like MonadIO into Futures, but be prepared for additional complexity since fpRust uses its own handlers and may not integrate directly with Tokio's executor without custom adaptation.

Question 2

fpRust vs RxRust for reactive streams?

Accepted Answer

fpRust's MonadIO is similar to RxRust but comes bundled with FP utilities and concurrency models. RxRust might be more focused and optimized for reactive programming alone, so choose based on whether you need the extra FP features or a leaner solution.

Question 3

Is fpRust production ready for large projects?

Accepted Answer

It has CI and crates.io presence, but its niche focus and complex abstractions mean it requires thorough testing. Check GitHub for recent activity and issue resolution before adopting in critical systems.

Question 4

How to handle errors in fpRust monads and actors?

Accepted Answer

The README doesn't detail error handling; likely, you'll need to use Rust's Result type or custom patterns within the monadic or actor contexts, consulting the documentation or source code for specifics.

Question 5

Can I replace async/await with fpRust coroutines?

Accepted Answer

Yes, fpRust coroutines support async/sync modes and can be integrated via Futures, but they involve manual handler management and mutexes, making them more complex than native async/await for simple tasks.

Question 6

What are the performance costs of fpRust actors?

Accepted Answer

Actors use message passing and internal states, which add overhead compared to direct threading or channels. Benchmark in your app, as the abstraction might impact latency in high-throughput scenarios.
