aion-server 0.9.0

Aion workflow server library: HTTP, gRPC, WebSocket, and worker endpoints. Run it with the `aion` binary from the aion-cli crate.
Documentation
//! Server-side outbox completion delivery callback.
//!
//! Bridges an unmatched durable-outbox completion arriving at the worker sink
//! ([`PendingActivities`](super::bridge::PendingActivities)) to the engine: it
//! resolves the workflow to its live process through the engine's active
//! registry and delivers the terminal into that workflow's mailbox, where the
//! engine's `take_and_record` records it. Installed only when the outbox is
//! enabled, so flag-off the unmatched branch stays a silent drop.
