React Loop Guard trait

Each method corresponds to an abnormal branch, returns GuardAction to decide next step. Implementors can:

• Use Focus for intelligent judgment
• Use counters + thresholds
• Pass through or intercept directly

Required Methods

fn on_reasoning_only<'life0, 'life1, 'async_trait>( &'life0 self, ctx: &'life1 GuardCtx, ) -> Pin<Box<dyn Future<Output = GuardAction> + Send + 'async_trait>>

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

Model returns only reasoning, no text/tool call

fn on_empty_response<'life0, 'life1, 'async_trait>( &'life0 self, ctx: &'life1 GuardCtx, ) -> Pin<Box<dyn Future<Output = GuardAction> + Send + 'async_trait>>

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

Model returns empty (no text, no reasoning, no tool call)

fn on_text_only<'life0, 'life1, 'async_trait>( &'life0 self, ctx: &'life1 GuardCtx, ) -> Pin<Box<dyn Future<Output = GuardAction> + Send + 'async_trait>>

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

Model returns text-only (no tool call)

Note: This method is called after middleware. If middleware has set follow_up_message, this branch won’t be entered.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
