Module context 

Script execution context ports.

When a job is scheduled, Chronon stores actor_json on the job record. When a worker dispatches the script, it calls ContextFactory::build to reconstruct handler context from that JSON. Script handlers (including those defined with #[chronon::script]) receive the result as Box<dyn ScriptContext>.

Choosing a factory

Approach	When to use
JsonScriptContextFactory	Examples, smoke tests, and handlers that only need ScriptContext::label and ScriptContext::actor_json
Custom ContextFactory	Production apps that map actor JSON to sessions, permissions, database access, or other application identity

Install the factory at runtime boot on ChrononBuilder (see chronon-runtime).

Structs

IdentityError

Identity reconstruction failure.

JsonScriptContextFactory

Default factory that wraps actor JSON in a labeled ScriptContext.

NoOpContextFactory

Factory that always returns NoOpScriptContext.

NoOpScriptContext

No-op context for tests and benchmarks.

Traits

ContextFactory

Builds a ScriptContext from JSON captured at schedule time.

ScriptContext

Opaque execution context for script handlers.
