Highly-available Distributed* Fault-tolerant Runtime
Bastion is a highly-available, fault-tolerant runtime system with dynamic, dispatch-oriented, lightweight process model. 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.
Please note that Bastion is not production-ready yet and might break some backward compatibility for now.
Bastion comes with a default one-for-one strategy root supervisor. You can use this to launch automatically supervised tasks.
- Message-based communication makes this project a lean mesh of actor system.
- Without web servers, weird shenanigans, forced trait implementations, and static dispatch.
- Runtime fault-tolerance makes it a good candidate for distributed systems.
- If you want the smell of Erlang and the powerful aspects of Rust. That's it!
- Completely asynchronous runtime with NUMA-aware and cache-affine SMP executor.
- Exploiting hardware locality wherever it is possible. It is designed for servers.
- Supervision system makes it easy to manage lifecycles.
- Kill your application in certain condition or restart you subprocesses whenever a certain condition is met.
- At most once delivery for all the messages.
- Completely asynchronous system design.
- Asynchronous program boundaries with fort.
- Dynamic supervision of supervisors (adding a subtree later during the execution)
- Lifecycle management both at
futuresand lightproc layers.
- Faster middleware development.
- Above all "fault-tolerance".
If one of the questions below answered with yes, then Bastion is just for you:
- Do I need fault-tolerancy in my project?
- Do I hate to implement weird Actor traits?
- I shouldn't need a webserver to run an actor system, right?
- Do I want to make my existing code unbreakable?
- Do I have some trust issues with orchestration systems?
- Do I want to implement my own application lifecycle?

Include bastion to your project with:
bastion = "0.3"
For more information please check Bastion Documentation
Runtime is structured by the user. Only root supervision comes in batteries-included fashion. Worker code, worker group redundancy, supervisors and their supervision strategies are defined by the user.
