## Async/sync duality via generators
|
|
|
|
All core logic is written once as a `Generator` function (`function *`). Use `yield` where you'd normally `await` a potentially async value.
|
|
|
|
- `toPromise(generator)` drives it **asynchronously** — awaits yielded promises.
|
|
- `toValueSync(generator)` drives it **synchronously** — passes yielded values through as-is.
|
|
|
|
Never duplicate logic into separate async and sync methods. A single generator serves both paths.
|
|
|
|
When wrapping an async+sync function pair (e.g. `contains`/`containsSync`, `exists`/`existsSync`, `readFile`/`readFileSync`), use `toLiquidAsync(syncFn, asyncFn?)` which returns a `LiquidAsync<F>` — one function that picks the sync or async implementation based on a leading `sync: boolean` arg. Then `yield` the result inside a generator to let the driver handle it in both modes.
