iterator: AsyncIterable<T>

Methods

collect(): Promise<T[]>

Collect the items in this iterator to an array.

concurrentMap(mapFn: (item: T) => Promise, concurrency?: number): AsyncIter

Map the sequence from one type to another, concurrently.

Results are returned in order.

concurrentUnorderedMap(mapFn: (item: T) => Promise, concurrency?: number): AsyncIter

Map the sequence from one type to another, concurrently.

Items are iterated out of order. This allows maximum concurrency at all times, but the output order cannot be assumed to be the same as the input order.

filter(filterFn: (item: T) => boolean | Promise<boolean>): AsyncIter<T>

Filter the sequence to contain just the items that pass a test.

first(): Promise<T | null>

Return the first item of the sequence.

flatten(): AsyncIter

Flatten the iterable.

forEach(forEachFn: (item: T) => void | Promise<void>): Promise<void>

Perform an operation for each item in the sequence.

map(mapFn: (item: T) => U | Promise): AsyncIter

Map the sequence from one type to another.

reduce(zero: U, reduceFn: (acc: U, item: T) => U | Promise): Promise

Reduce a sequence to a single value.
