unfoldAsync
unfoldAsync<
S,T>(seed,next):AsyncIterableIterator<T>
Defined in: packages/core/src/iterable/async/unfold.ts:17
Generates a sequence from a seed, one step at a time — the dual of reduce.
The async counterpart of unfold, and the shape a paginated API has: the
state is the cursor, and next resolves to the page plus the cursor that
follows it, or undefined when there are no more.
Time complexity: O(1) per element, plus whatever next costs.
Type Parameters

T
Parameters
Section titled “Parameters”S
The initial state.
MaybeAsyncCallable<[S], readonly [T, S] | undefined>
Receives the current state and resolves to [value, nextState],
or undefined to end the sequence.
Returns
Section titled “Returns”AsyncIterableIterator<T>
An iterator over the generated values.
