variable AsyncReducer.pipe
import { AsyncReducer } from "https://deno.land/x/rimbu@1.2.1/mod.ts";
const { pipe } = AsyncReducer;

Returns an AsyncReducer instance that first applies this reducer, and then applies the given next reducer to each output produced by the previous reducer.

Examples

Example 1

AsyncStream
 .from(Stream.of(1, 2, 3))
 .reduce(
   AsyncReducer.pipe(Reducer.product, Reducer.sum)
 )
// => 9

type

{ <I, O1, O2>(reducer1: AsyncReducer.Accept<I, O1>, reducer2: AsyncReducer.Accept<O1, O2>): AsyncReducer<I, O2>; <I, O1, O2, O3>(
reducer1: AsyncReducer.Accept<I, O1>,
reducer2: AsyncReducer.Accept<O1, O2>,
reducer3: AsyncReducer.Accept<O2, O3>,
): AsyncReducer<I, O3>; <I, O1, O2, O3, O4>(
reducer1: AsyncReducer.Accept<I, O1>,
reducer2: AsyncReducer.Accept<O1, O2>,

): AsyncReducer<I, O4>; <I, O1, O2, O3, O4, O5>(
