Struct BudgetConfig 

pub struct BudgetConfig {
    pub max_tool_calls: Option<usize>,
    pub max_tokens: Option<usize>,
    pub max_duration: Option<Duration>,
    pub max_iterations: Option<usize>,
    pub max_cost_usd: Option<f64>,
}

Hard budget for the agent control loop. A None field means that item is unlimited.

Fields

max_tool_calls: Option<usize>

Cumulative tool-call cap (parallel calls included; stops when exceeded).

max_tokens: Option<usize>

Cumulative LLM output-token cap (reads AgentMetrics.total_tokens; has no effect when the agent does not report tokens).

max_duration: Option<Duration>

Loop wall-clock cap (timed from run_agent_loop).

max_iterations: Option<usize>

Iteration cap (tightens AgentExecutor::max_iterations; hitting it returns an error instead of the placeholder return path used at the iteration limit).

max_cost_usd: Option<f64>

Cumulative USD spend cap (read from the shared lc_core::cost::CostTracker; has no effect when the executor carries no cost tracker). Measured after each LLM call.
