Struct ToolCallLoopGuard 

pub struct ToolCallLoopGuard { /* private fields */ }

Detects consecutive identical assistant tool calls across model turns.

Implementations

impl ToolCallLoopGuard

pub fn new(options: ToolCallLoopGuardOptions) -> Self

Construct from options. threshold is clamped to ≥ 1.

pub fn with_threshold(self, threshold: usize) -> Self

Override the threshold at runtime.

pub fn with_exempt_tool(self, tool: impl Into<String>) -> Self

Mark a tool as exempt from detection.

pub fn record_turn( &mut self, turn: ToolCallLoopTurn<'_>, ) -> Option<RepeatedToolCallDetection>

Records one completed turn and returns the threshold hit, if any.

A “completed turn” is one assistant message that contained tool calls and for which the corresponding tool results have been emitted. Turns with multiple distinct tool calls reset detection.

pub fn reset(&mut self)

Reset state between unrelated runs (e.g. on session boundary).

Trait Implementations

impl Debug for ToolCallLoopGuard

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

Formats the value using the given formatter.

impl Default for ToolCallLoopGuard

fn default() -> Self

Returns the “default value” for a type.
