Struct Thread 

pub struct Thread {
    pub id: String,
    pub resource_id: Option<String>,
    pub parent_thread_id: Option<String>,
    pub metadata: ThreadMetadata,
    pub active_run_id: Option<String>,
    pub open_run_id: Option<String>,
    pub latest_run_id: Option<String>,
    pub latest_run_updated_at: Option<u64>,
}

A persistent conversation thread (metadata only).

Messages are stored separately via ThreadStore::load_messages / ThreadStore::save_messages to maintain a single source of truth.

Fields

id: String

Unique thread identifier (UUID v7).

resource_id: Option<String>

External resource or tenant grouping for this thread.

parent_thread_id: Option<String>

Parent thread for child or delegated conversations.

metadata: ThreadMetadata

Thread metadata (timestamps, title, custom data).

active_run_id: Option<String>

Run currently executing on a worker for this thread.

open_run_id: Option<String>

Current unfinished user intent for this thread. Waiting runs remain open.

latest_run_id: Option<String>

Most recently known run for this thread.

latest_run_updated_at: Option<u64>

updated_at watermark for the projected latest run.
