Documentation

aion-server

The Aion server library: HTTP, gRPC, WebSocket, and worker-protocol endpoints for Aion workflows. The crate wraps the transport-agnostic engine with API handlers, namespace isolation, observability, shutdown handling, dashboard assets, and remote-worker task dispatch.

This crate ships no binary. To run an Aion server, install the CLI and use the server subcommand:

cargo install aion-cli --locked
aion server --config aion.toml

Configuration (required keys, defaults, AION_* environment overrides) is documented in the repository's operations guide.
