namespace pw::thread {
// An optional virtual interface which can be implemented by objects which are
// a thread as a helper to use pw::thread::Thread.
// This wrapper means that the user is not required to provide the indirection
// callback to call run based on the passed context. For example instead of:
// static auto invoke_foo_start = [](void *void_foo_ptr) {
// static_cast<Foo*>(void_foo_ptr)->Start();
// };
// Thread thread(options, invoke_foo_start, &foo).detach();
// You can instead use the helper constructor in Thread:
// Thread thread(options, foo).detach();
// WARNING: Because the thread may start after the pw::Thread creation, an
// object which implements the ThreadCore MUST meet or exceed the lifetime of
// its thread of execution!
