Staged Event-Driven Architecture (SEDA) Bus

A form of message bus avoiding the high overhead of thread-based concurrency models where channels get their own inbound and outbound queues. When used in conjunction with the Service Bus, the service bus acts as a layer above the message bus driving routing based on service operations and/or other logic which results in mappings to the lower message bus address.

Design Goals

*[x] non-persistence of messages for deniability by default *[ ] mark messages as consumed on consumption so that clients can continue on if synchronous *[ ] mark messages as completed on completion so that clients know when they can clear the queue if they wish *[ ] mark messages as errored with code on error so that clients can determine how they wish to handle it *[ ] use dbus for inter-process communications on Linux *[ ] use ipcd for inter-process communications on RedoxOS

Functionality

lib.rs

1. Start Bus
2. Register Endpoints as needed using Bus receiving Id
3. Send Envelopes
4. Poll with Ids

main.rs

1. cargo install seda_bus
2. copy sedabus file to: /etc/init.d/sedabus
3. chmod +x /etc/init.d/seda_bus -v
4. service seda_bus start
