Crate chronon_core 

Chronon core — portable types and the SchedulerStore persistence port.

This crate defines domain models, error types, script identity ports, and the async storage trait that backends implement. It has no runtime, scheduler, or HTTP dependencies.

Goals

• Stable DTOs (Job, Run, Script) shared by scheduler, executor, and adapters
• A single SchedulerStore port for jobs, runs, leases, and coordinator metadata
• Host-injectable script identity via ScriptContext and ContextFactory

Non-goals

• Running tick loops or executing scripts (see chronon-runtime and chronon-executor)
• Choosing a storage backend (hosts register implementations at boot)

Modules

• store — SchedulerStore trait and persistence contract
• models — jobs, runs, revisions, workers, schedule enums
• context — ScriptContext and ContextFactory for script dispatch
• router — named store registration via StoreRouter
• error — ChrononError and Result

Getting started

Implement SchedulerStore for your storage substrate, then register it on StoreRouter::register_global or pass the store directly to ChrononBuilder in chronon-runtime.
