Struct NoopBudgetGuard 

pub struct NoopBudgetGuard;

Default implementation that always allows everything. Used when no host-supplied guard is configured.

Trait Implementations

impl BudgetGuard for NoopBudgetGuard

fn check_before_llm<'life0, 'life1, 'async_trait>( &'life0 self, session_id: &'life1 str, estimated_prompt_tokens: usize, ) -> Pin<Box<dyn Future<Output = BudgetDecision> + Send + 'async_trait>>

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

Called immediately before an LLM API call.

fn record_after_llm<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, session_id: &'life1 str, usage: &'life2 TokenUsage, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

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

Called after every successful LLM call with the actual usage reported by the provider. Lets the impl keep its running spend total in sync with reality.

fn check_before_tool<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, session_id: &'life1 str, tool_name: &'life2 str, ) -> Pin<Box<dyn Future<Output = BudgetDecision> + Send + 'async_trait>>

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

Called immediately before a tool invocation. The framework does not pass tool arguments — impls that need argument-aware caps must wrap the executor via a custom ToolExecutor.

fn clone(&self) -> NoopBudgetGuard

Returns a duplicate of the value.

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

Performs copy-assignment from source.
