💎 Async Operations in TuskLang - Ruby Edition

"We don't bow to any king" - Asynchronous Processing with Ruby Power

Async operations in TuskLang provide powerful asynchronous processing capabilities, allowing you to handle concurrent operations, background jobs, and real-time processing. In Ruby, this integrates seamlessly with Rails, Sidekiq, and provides advanced async patterns that go beyond traditional synchronous approaches.

🎯 Summary

TuskLang's async operations system in Ruby provides:

- Background job processing with Sidekiq integration - Event-driven async operations with Redis event bus - Parallel execution for concurrent task processing - Async/await patterns for clean asynchronous code - Rails integration with ActiveRecord and ActionMailer - Delayed and recurring jobs for scheduled processing - Testing frameworks for async operation validation - Security features for safe async execution - Custom rake tasks for async operation management

The Ruby implementation maintains TuskLang's rebellious spirit while providing enterprise-grade async capabilities that "don't bow to any king" - not even the constraints of traditional synchronous processing patterns.
