L15: Contexts and Dispatchers

Lesson in Preparation (WIP)

This lesson is currently undergoing pedagogical drafting and development. It will soon be available with detailed visual diagrams, in-depth explanations, and its corresponding milestone in the AI Chat CLI incremental lab.

What will you learn in this lesson?

In this lesson we will explore:

• Deep Theory: Elements of CoroutineContext, safe thread switching with withContext, specific roles of Dispatchers.IO, Dispatchers.Default, and Dispatchers.Unconfined, and exception handling with CoroutineExceptionHandler.
• Under the Hood: How Dispatchers back onto adaptive JVM thread pools (ForkJoinPool / worker threads).
• Incremental Lab (AI Chat CLI): Isolating blocking network calls to remote AI APIs onto Dispatchers.IO while processing token streaming on Dispatchers.Default.
