Module workflow_simulation 

Workflow simulation (dry-run) engine.

Traces the execution path of a workflow DAG without actually running any tasks. Useful for pre-flight validation, capacity planning, cost estimation, and debugging complex conditional workflows.

The simulator walks the DAG in topological order, evaluates edge conditions against simulated outputs, and produces a detailed execution trace showing which nodes would run, be skipped, or potentially fail.

Structs

EvaluatedCondition

Result of evaluating an edge condition during simulation.

SimulationConfig

Configuration for a simulation run.

SimulationReport

A simple simulation report produced by dry-running a crate::workflow::Workflow.

SimulationResult

SimulationSummary

Summary statistics from a simulation.

SimulationTraceEntry

A single entry in the simulation trace.

WorkflowDryRun

Dry-run simulator for crate::workflow::Workflow.

WorkflowSimulator

The workflow simulation engine.

Enums

How a condition was resolved.

SimulatedOutcome

Outcome of a simulated node execution.

Functions

quick_simulate

Helper to create a simple simulation for a DAG.
