Implementations

impl Engine

pub async fn new( workflow: WorkflowDef, target: String, vars: HashMap<String, Value>, verbose: bool, quiet: bool, ) -> Self

pub async fn with_options( workflow: WorkflowDef, target: String, vars: HashMap<String, Value>, options: EngineOptions, ) -> Self

pub fn step_records(&self) -> &[StepRecord]

Return collected step records (for JSON output or testing)

pub fn json_output( &self, status: &str, total_duration: Duration, ) -> WorkflowJsonOutput

Build the JSON summary after execution

pub async fn run(&mut self) -> Result<StepOutput>

pub async fn execute_step( &mut self, step_def: &StepDef, ) -> Result<StepOutput, StepError>

pub fn dry_run(&self)

Dry-run: walk all steps and print a visual tree without executing anything.
