Struct LlmUserSimulator 

pub struct LlmUserSimulator { /* private fields */ }

A simulator that drives a user LLM with a persona + template. Each respond call builds a CompletionRequest whose system prompt is the rendered prompt_template (with {persona} and {task} substituted) and whose user message is the serialized conversation so far.

The simulator looks for a terminal sentinel — by default <end> — in the LLM’s response to decide whether to return UserAction::EndConversation. The sentinel is matched case-insensitively and stripped from the surrounding text.

Implementations

impl LlmUserSimulator

pub fn default_template() -> &'static str

A reasonable default template — users with opinionated simulators should supply their own.

pub fn new( llm: Arc<dyn Llm>, persona: impl Into<String>, prompt_template: impl Into<String>, ) -> Self

pub fn with_end_sentinel(self, sentinel: impl Into<String>) -> Self

pub fn with_name(self, name: impl Into<String>) -> Self

Trait Implementations

impl UserSimulator for LlmUserSimulator

fn name(&self) -> &str

fn initial_message<'life0, 'life1, 'async_trait>( &'life0 self, task: &'life1 Task, ) -> Pin<Box<dyn Future<Output = Result<String, UserError>> + Send + 'async_trait>>

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

Produce the first user message from the task. Called once at the start of a conversation loop.

fn respond<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, conversation: ConversationView<'life1>, task: &'life2 Task, ) -> Pin<Box<dyn Future<Output = Result<UserAction, UserError>> + Send + 'async_trait>>

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

Respond to the current conversation. Return UserAction::Say with the next user message, or UserAction::EndConversation to terminate the loop.
