Detailed Description

template<typename Fn>
struct Foundation::Core::ParallelForAsyncState< Fn >

Heap-resident shared state for a non-blocking ThreadPool::ParallelForAsync.

Unlike the stack-resident ParallelForJob (whose lifetime is bounded by the blocking call), an async parallel-for must outlive the scheduling call: the caller returns immediately with a Future and does not participate. The functor, the shared cursor, the fork-join latch and the Promise all live here; the last worker to drain satisfies the promise and frees the state.
