Struct ExecutionLimits 

pub struct ExecutionLimits {
    pub max_turns: usize,
    pub max_total_tokens: usize,
    pub max_duration: Duration,
    pub max_cost: Option<f64>,
}

Execution limits for the agent loop — guards against infinite loops and budget overruns.

Fields

max_turns: usize

Maximum number of LLM turns (one turn = one LLM call + its tool results)

max_total_tokens: usize

Maximum total tokens consumed across all turns (input + output)

max_duration: Duration

Maximum wall-clock duration. Uses std::time::Duration (not f64 seconds) for precision.

max_cost: Option<f64>

Maximum cumulative dollar cost for the run. None means no cost cap. Requires AgentLoopConfig.cost_config to be set — without pricing rates the accumulated cost is always 0.0 and this limit has no effect.

Trait Implementations

impl Clone for ExecutionLimits

fn clone(&self) -> ExecutionLimits

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExecutionLimits

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ExecutionLimits

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ExecutionLimits

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for ExecutionLimits

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,
