Struct ToolCallLimitMiddleware 

pub struct ToolCallLimitMiddleware { /* private fields */ }

Limits the number of tool invocations during a single agent run.

When the limit is exceeded, wrap_tool_call returns a SynapticError::MaxStepsExceeded error.

Implementations

impl ToolCallLimitMiddleware

pub fn new(max_calls: usize) -> Self

pub fn call_count(&self) -> usize

pub fn reset(&self)

Trait Implementations

impl AgentMiddleware for ToolCallLimitMiddleware

fn wrap_tool_call<'life0, 'life1, 'async_trait>( &'life0 self, request: ToolCallRequest, next: &'life1 dyn ToolCaller, ) -> Pin<Box<dyn Future<Output = Result<Value, SynapticError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Wraps a tool call. Override to intercept or replace tool execution.

fn before_agent<'life0, 'life1, 'async_trait>( &'life0 self, _messages: &'life1 mut Vec<Message>, ) -> Pin<Box<dyn Future<Output = Result<(), SynapticError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Called once when the agent starts executing.

fn after_agent<'life0, 'life1, 'async_trait>( &'life0 self, _messages: &'life1 mut Vec<Message>, ) -> Pin<Box<dyn Future<Output = Result<(), SynapticError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Called once when the agent finishes executing.

fn before_model<'life0, 'life1, 'async_trait>( &'life0 self, _request: &'life1 mut ModelRequest, ) -> Pin<Box<dyn Future<Output = Result<(), SynapticError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Called before each model invocation. Can modify the request.

fn after_model<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _request: &'life1 ModelRequest, _response: &'life2 mut ModelResponse, ) -> Pin<Box<dyn Future<Output = Result<(), SynapticError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Called after each model invocation. Can modify the response.

fn wrap_model_call<'life0, 'life1, 'async_trait>( &'life0 self, request: ModelRequest, next: &'life1 dyn ModelCaller, ) -> Pin<Box<dyn Future<Output = Result<ModelResponse, SynapticError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Wraps the model call. Override to intercept or replace the model invocation.
