Module flow 

Flow definition types for YAML deserialization.

This module provides strongly-typed structures for parsing YAML flow definitions:

• FlowDefinition - The top-level flow document
• NodeDefinition - Individual node configuration
• EdgeDefinition - Connection between nodes
• TriggerDefinition - Trigger configuration

Example YAML

name: order_processing
version: "1.0"
description: Process incoming orders

triggers:
  - id: webhook_in
    type: webhook
    params:
      port: 8080
      path: /orders

nodes:
  fraud_check:
    type: std::switch
    config:
      condition:
        type: greater_than
        field: risk_score
        value: 0.8

  high_risk:
    type: std::log
    config:
      message: "High risk order detected"

edges:
  - from: webhook_in
    to: fraud_check
  - from: fraud_check.true
    to: high_risk

settings:
  max_concurrent_executions: 100
  execution_timeout_ms: 60000
