Struct PromptManager 

pub struct PromptManager { /* private fields */ }

Prompt manager

Tracks active prompts per session and ensures serialization:

• Only one prompt can run at a time per session
• New prompts automatically cancel old prompts
• Provides timeout protection for cancellation

Implementations

impl PromptManager

pub fn new() -> Self

Create a new prompt manager

pub async fn cancel_session_prompt(&self, session_id: &str) -> bool

Cancel any active prompt for the given session

This will:

1. Send a cancellation signal via the token
2. Wait for the task to complete (with 5 second timeout)
3. Remove the task from tracking

Returns true if an old prompt was cancelled, false if there was no active prompt for this session.

pub fn register_prompt( &self, session_id: String, handle: JoinHandle<()>, cancel_token: CancellationToken, ) -> PromptId

Register a new prompt task

This should be called after spawning a prompt task. The prompt will be tracked and can be cancelled later.

pub fn complete_prompt(&self, session_id: &str, prompt_id: &str)

Mark a prompt as completed

This should be called when a prompt finishes normally (not cancelled). It removes the prompt from tracking if the prompt_id matches.

pub fn active_count(&self) -> usize

Get the number of active prompts

pub fn has_active_prompt(&self, session_id: &str) -> bool

Check if a session has an active prompt
