pull‑defer provides a tiny utility for the Pull‑Stream ecosystem that creates “deferred” streams—place‑holders for sources, sinks, or through (transform) streams that stay idle until you explicitly attach a real stream with `resolve` (or `start`). It lets developers compose pipelines where the actual data flow can be hooked up later, useful for coordinating asynchronous setup in Node.js applications. Suitable for developers building modular, lazy‑loaded or dynamically‑wired Pull‑Stream pipelines.
