Methods

collect(): Promise<T[]>

Collect the items in this iterator to an array.

concurrentMap<U>(mapFn: (item: T) => Promise<U>, concurrency?: number): Runnable<U>

Map the sequence from one type to another, concurrently.

Results are returned in order.

concurrentUnorderedMap<U>(mapFn: (item: T) => Promise<U>, concurrency?: number): Runnable<U>

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>): Runnable<T>

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

flatten(): Runnable<ElementType<T>>

Flatten the iterable.

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

Perform an operation for each item in the sequence.

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

Map the iterator from one type to another.

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

Reduce a sequence to a single value.

run<S>(options: ProcessOptions<S>, ...cmd: Cmd): Runnable<Uint8Array>

Run a process.

run(...cmd: Cmd): Runnable<Uint8Array>

Run a process.

tee<N extends number = 2>(n?: N): Tuple<AsyncIterable<T>, N>
transform<U>(fn: (it: AsyncIterable<T>) => AsyncIterable<U>): Runnable<U>

Transform the iterable from one type to another with an opportunity to catch and handle errors.

Write all data to the writer.

Note that this call returns immediately, although it continues to run until the source iterable data is exhausted.
