Struct ErrorHandler 

pub struct ErrorHandler;

Handles step execution errors and applies error actions

Responsible for:

• Catching step execution errors
• Applying error actions (retry, skip, fail, rollback)
• Tracking error history
• Managing retry logic with exponential backoff

Implementations

impl ErrorHandler

pub fn handle_error( workflow: &Workflow, state: &mut WorkflowState, step_id: &str, error: String, ) -> WorkflowResult<bool>

Handle a step execution error

Applies the specified error action and updates the workflow state accordingly. Returns true if the workflow should continue, false if it should stop.

pub fn should_retry(workflow: &Workflow, step_id: &str) -> bool

Check if a step should be retried

pub fn get_retry_config( workflow: &Workflow, step_id: &str, ) -> Option<(usize, u64)>

Get retry configuration for a step

pub fn should_skip_on_error(workflow: &Workflow, step_id: &str) -> bool

Check if a step should be skipped on error

pub fn should_rollback_on_error(workflow: &Workflow, step_id: &str) -> bool

Check if a step should rollback on error

pub fn get_error_action( workflow: &Workflow, step_id: &str, ) -> Option<ErrorAction>

Get the error action for a step

pub fn capture_error( state: &mut WorkflowState, step_id: &str, error_type: &str, error_message: &str, stack_trace: Option<&str>, ) -> WorkflowResult<()>

Capture error details in step result

Stores error type, message, and stack trace in the step result.

pub fn get_error_details(state: &WorkflowState, step_id: &str) -> Option<String>

Get error details from a step result

pub fn has_error(state: &WorkflowState, step_id: &str) -> bool

Check if a step has an error

pub fn get_all_errors(state: &WorkflowState) -> Vec<(String, String)>

Get all errors in the workflow
