Struct LongRunningExecutionPolicy 

pub struct LongRunningExecutionPolicy {
    pub max_discovered_steps: Option<u32>,
    pub max_discovery_depth: Option<u32>,
    pub cost_alert_threshold_usd: Option<f64>,
    pub idle_timeout_seconds: Option<u64>,
    pub max_same_step_repetitions: Option<u32>,
}

Policy configuration for long-running agentic executions

These controls prevent runaway costs, infinite discovery loops, and idle executions from consuming resources in the Agentic DAG model.

Fields

max_discovered_steps: Option<u32>

Maximum number of dynamically discovered steps before intervention (Steps with StepSource::Discovered)

max_discovery_depth: Option<u32>

Maximum depth of discovery chains (prevents infinite discovery) e.g., agent discovers step A, which discovers step B, which discovers C…

cost_alert_threshold_usd: Option<f64>

Alert threshold for cumulative cost in USD When exceeded, execution pauses for approval

idle_timeout_seconds: Option<u64>

Maximum time without activity before idle timeout (seconds)

max_same_step_repetitions: Option<u32>

Maximum repetitions of same methodology before loop detection (default: 3)

Implementations

impl LongRunningExecutionPolicy

pub fn standard() -> Self

Standard preset - balanced limits for typical long-running executions

• Max duration: ~30 minutes (via idle timeout)
• Discovered steps: 50
• Discovery depth: 5
• Cost alert: $5.00 USD

pub fn extended() -> Self

Extended preset - higher limits for complex, supervised workflows

• Max duration: ~4 hours
• Discovered steps: 300
• Discovery depth: 10
• Cost alert: $50.00 USD

pub fn unlimited() -> Self

Unlimited preset - no discovery limits, but requires cost monitoring

• No step/depth limits
• Cost alert: $100.00 USD (mandatory safety net)
• Idle timeout: 24 hours

pub fn disabled() -> Self

Disabled - no long-running controls (use with caution)
