actionqueue-engine

Scheduling, derivation, and concurrency primitives for the ActionQueue task queue engine.

Overview

This crate provides the scheduling engine:

• derive -- Run derivation from task specifications (Once, Repeat, Cron)
• index -- Run indexing by state (Scheduled, Ready, Running, Terminal)
• selection -- Priority + FIFO run selection for executor leasing
• scheduler -- State promotion (Scheduled to Ready, RetryWait to Ready)
• lease -- Lease ownership and expiry models
• concurrency -- Concurrency key gates for single-flight execution control
• time -- Clock trait abstraction for deterministic testing
