Module runtime 

Runtime support for the #[durable_execution] macro.

This module contains the runtime logic that was previously generated inline by the proc macro. By extracting it into library code, we get:

• Unit-testable runtime logic
• A single copy in the binary (no per-handler duplication)
• Readable error messages pointing to real source files
• Bug fixes ship in the SDK crate, not the macro crate

Users typically don’t interact with this module directly — the #[durable_execution] macro calls run_durable_handler automatically. However, advanced users can call it directly to skip the macro.

Requirements

• 15.1: THE Lambda_Integration SHALL provide a #[durable_execution] attribute macro for handler functions
• 15.3: THE Lambda_Integration SHALL create ExecutionState and DurableContext for the handler

Functions

extract_event

Extracts the user’s event from a DurableExecutionInvocationInput.

run_durable_handler

Runs a durable execution handler within the Lambda runtime.
