promiseWithLoop

fnPromise!T promiseWithLoop(T)(EventLoop * loop, CompletionPolicy policy = CompletionPolicy.DEFERRED) @trusted

Create a promise/future pair with EventLoop integration.

When policy is CompletionPolicy.DEFERRED, callbacks registered via then()/onError()/onCancel() are queued via EventLoop.defer() and execute on the next loop iteration. This prevents reentrancy and guarantees callbacks run on the loop thread.

Parameters

`loop`	EventLoop to use for deferred completion.
`policy`	Completion policy (default: DEFERRED).
`T`	The type of value the future will hold.

Returns

A new promise with EventLoop integration.
