Crate tauri_queue 

Tauri Queue

Tauri integration for the agent-queue background job processing system.

This crate provides a TauriEventEmitter that bridges job-queue events to Tauri’s frontend event system, plus re-exports of all core job-queue types.

Quick Start

1. Define a job type implementing JobHandler
2. Create a QueueManager with a QueueConfig
3. Add jobs with QueueManager::add()
4. Spawn the executor with QueueManager::spawn() using a TauriEventEmitter
