481 * @brief Try-safe access to an InlineHook by its ID using a non-blocking lock.
482 * @details Provides a non-blocking alternative to with_inline_hook(). The callback
483 * is invoked only if the lock is immediately acquired via std::try_to_lock.
484 * Note: try_to_lock only avoids blocking on initial acquisition - it does NOT
485 * make callbacks safe to re-enter HookManager methods that also acquire the
486 * same non-recursive mutex (e.g., enable_hook, disable_hook). If a callback
487 * needs to call those methods, it must release the lock first or perform those
488 * calls asynchronously to avoid deadlock. See with_inline_hook for the blocking
489 * analogue.
490 * @param hook_id The name of the inline hook.
491 * @param fn The callback to invoke with the hook reference.
492 * @return std::optional<R> The callback's return value. Returns std::nullopt if either
493 * the lock could not be acquired or the hook was not found.

559 * @brief Try-safe access to a MidHook by its ID using a non-blocking lock.
560 * @details Provides a non-blocking alternative to with_mid_hook(). The callback
561 * is invoked only if the lock is immediately acquired via std::try_to_lock.
562 * Note: try_to_lock only avoids blocking on initial acquisition - it does NOT
563 * make callbacks safe to re-enter HookManager methods that also acquire the
564 * same non-recursive mutex (e.g., enable_hook, disable_hook). If a callback
565 * needs to call those methods, it must release the lock first or perform those
566 * calls asynchronously to avoid deadlock. See with_mid_hook for the blocking
567 * analogue.
568 * @param hook_id The name of the mid hook.
569 * @param fn The callback to invoke with the hook reference.
570 * @return std::optional<R> The callback's return value. Returns std::nullopt if either
571 * the lock could not be acquired or the hook was not found.
