Module runtime 

Available on crate feature runtime only.

A small reference runtime.

The core Machine trait is pure and does not own mode. Real systems need a loop that:

• stores the current mode
• feeds external events into the machine
• applies mode changes (optionally checking a Policy)
• dispatches emitted commands to the outside world

This module provides a minimal, synchronous helper for that loop. It does not provide an event queue, scheduler, or async runtime.

Runner

Owns the current mode and feeds events into a Machine.
