Enum LoopAction 

pub enum LoopAction {
    Warn,
    Stop,
    InjectWarning,
}

Action to take when a tool call loop is detected.

Variants

Warn

Emit LoopEvent::LoopDetected and continue execution.

Use this for monitoring/alerting without interrupting the agent.

Stop

Stop the loop immediately with an error.

Returns LlmError::ToolExecution describing the loop.

InjectWarning

Inject a warning message into the conversation and continue.

Adds a system message like “You have called {tool} with identical arguments {n} times. Try a different approach.” This often helps the agent break out of the loop.

The warning fires at every multiple of threshold (3, 6, 9, …) until the agent changes its approach. This prevents infinite loops where the agent ignores the first warning.

Trait Implementations

impl Clone for LoopAction

fn clone(&self) -> LoopAction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LoopAction

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

Formats the value using the given formatter.

impl PartialEq for LoopAction

fn eq(&self, other: &LoopAction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
