Summary

  • Add C++20 module support for thread_system (Tier 1 library)
  • Create module files following common_system structure
  • Update CMake configuration for module builds
  • Add documentation for module usage

Changes

Module Files Created

  • src/modules/thread.cppm: Primary module interface (kcenon.thread)
  • src/modules/core.cppm: Core partition with thread pool, workers, jobs
  • src/modules/queue.cppm: Queue partition with job_queue, adaptive_job_queue

CMake Updates

  • Add THREAD_BUILD_MODULES option (requires CMake 3.28+)
  • Create thread_system_modules target with CXX_MODULES file set
  • Auto-link to common_system modules or headers

Documentation

  • Add C++20 module section to README.md

Test Plan

  • Standard build passes (without modules)
  • CMake configuration succeeds with new options
  • Module build tested with CMake 3.28+ (optional - CI may not have 3.28)
  • Integration with common_system modules verified

Prerequisites Completed

Closes #371

Add C++20 module support for thread_system as part of Tier 1 core
libraries, following the module structure established in common_system.

Module structure:
- thread.cppm: Primary module interface (kcenon.thread)
- core.cppm: Core partition with thread pool, workers, jobs
- queue.cppm: Queue partition with job_queue, adaptive_job_queue

The module system wraps existing header-based implementations,
providing an alternative import mechanism while maintaining
backward compatibility with the header-only interface.

CMake changes:
- Add THREAD_BUILD_MODULES option (requires CMake 3.28+)
- Create thread_system_modules target with CXX_MODULES file set
- Link to common_system modules or headers as available

Refs: #371
Add section describing C++20 module support including:
- Requirements (CMake 3.28+, modern compilers)
- Build instructions with THREAD_BUILD_MODULES option
- Usage example with import statement
- Module structure table (thread, core, queue partitions)

* feat(modules): add C++20 module files for kcenon.thread

Add C++20 module support for thread_system as part of Tier 1 core
libraries, following the module structure established in common_system.

Module structure:
- thread.cppm: Primary module interface (kcenon.thread)
- core.cppm: Core partition with thread pool, workers, jobs
- queue.cppm: Queue partition with job_queue, adaptive_job_queue

The module system wraps existing header-based implementations,
providing an alternative import mechanism while maintaining
backward compatibility with the header-only interface.

CMake changes:
- Add THREAD_BUILD_MODULES option (requires CMake 3.28+)
- Create thread_system_modules target with CXX_MODULES file set
- Link to common_system modules or headers as available

Refs: #371

* docs: add C++20 module documentation to README

Add section describing C++20 module support including:
- Requirements (CMake 3.28+, modern compilers)
