Show HN: Coerce – Actor runtime for Rust using async/await and tokio channels

Worth to mention that Bastion has been developed a lot and it has its own design(in simple terms SMP based executor) to leverage asynchronous programming (with fault-tolerant manner). It isn't dependent on any runtime. You can mix and use any runtime with it and supplies hierarchical reduction based concurrency.

We proudly take Erlang's runtime model and implemented it in Rust. Moreover, we are currently working on distributed carrier protocol to make Bastion form a cluster, exchange data and recover from partial failures in distributed workloads too.

Local failures are recovered and we have built-in lifecycle management.

Maybe after these words you might want to take a look: https://github.com/bastion-rs/bastion

You can write a fully fault-tolerant program with our macro mechanisms too: https://github.com/bastion-rs/fort

Here our distributed protocol repository: https://github.com/bastion-rs/artillery

And our landing page: https://bastion.rs/

Not engaging at all with the thing shown and just talking about yours, without any comparison, seems fairly rude on a Show HN.

Rude to the users? Because users win when they see interesting competitors.

What are your thoughts about the project that you sidelined-- Coerce? That is what brought people here in the first place and the project deserves recognition.

I'm not familiar with this family of technology, so forgive the dumb question:

But.. what is this?

I read the landing page and browsed a couple examples and I have no clue what I would use it for.

Would it be a pile of distributed workers handling jobs? Sort of like pushing a job into a job queue and having a bunch of workers consume jobs?

If that's the case, what are some reasons I might choose this Bastion model over a more traditional JobQueue <-> Worker model?

Thanks to any replies. I feel I should be interested, but I'm confused :)

As landing page states it is a runtime supplies actor-model like concurrency. If you are familiar with Erlang. Bastion is the reflection of the Erlang runtime in Rust. Far beyond an actor system implementation. It is a complete system with full asynchronous communication.

"...It supplies actor-model-like concurrency with a lightweight process implementation and utilizes all of the system resources efficiently guaranteeing of at-most-once message delivery."

It might be a single process, pile of workers, a bunch of http servers dispatching requests, various middleware layers connected with asynchronous boundaries. With all these built on top of crash and fault recovery.

For more information what it provides please take a look to my latest presentation at Rust Berlin: https://slides.com/vertexclique/crash-course-with-bastion#/
