In-order Execution in Asynchronous Programming via Result Handlers

The patent introduces result handlers as intermediary components that mediate between asynchronous task completion and subsequent statement execution. The result handler receives the completion signal from the asynchronous task and triggers the execution of dependent statements, ensuring proper sequencing without blocking the main thread. This intermediary mechanism allows asynchronous operations to maintain both responsiveness and execution order control.

The patent replaces the mechanical blocking mechanism (synchronous waiting) with an event-driven mechanism using result handlers and callbacks. Instead of the main thread being mechanically blocked by synchronous calls, the system uses asynchronous event notification where result handlers are invoked automatically when tasks complete, substituting the blocking mechanical system with a non-blocking event-based system that maintains execution order.

The patent implements self-service through automatic result handler chaining and compiler-generated sequencing code. The system automatically manages the complex task of tracking asynchronous completions and triggering subsequent statements without requiring manual intervention or complex developer orchestration. The compiler and runtime automatically handle the sequencing logic, reducing development time while maintaining execution order control.
