task-scheduler

Task Scheduler in C++20. This is a header-only library.

Building

For testing and benchmarking, additional build commands are needed.

Requirements:

• Conan (for building the tests),
• GCC v12 or higher, or Clang v13 or higher,
• Clang-format v14 or higher,

Instructions:

mkdir build
ccmake -S . -B ./build/
cd build
make

Functional requirements

Aside from the common-sense requirements for correct, efficient and thread-safe implementation, there are functional requirements. The following requirements levels are as defined in RFC 2119.

MUST

• Support running tasks based on:
  • Class member functions,
  • Free functions,
  • Lambda expressions.
• Support the configuration of the amount of workers.
• Support the configuration of the work queue length.
• Support the graceful handling of exceptions.
• Support deferred return value propagation for task results. (TODO)

SHOULD

• Support the concept of task priority. (TODO)
• Support scheduling of automatic periodic tasks. (TODO)
• Support a configurable scheduling strategy. (TODO)
• Support a mode that keeps a strict task order. (TODO)

MAY

• Support small object optimization for task objects. (TODO)

Ideas

• Use if constexpr (std::is_void_v<T>) to detect tasks without a return value.
• Integrate std::expected into the completion token once C++23 is around.
