Package: effect
Module: Tuple

Tuple.makeCombiner

Creates a Combiner for a tuple shape by providing a Combiner for each position. When two tuples are combined, each element is merged using its corresponding combiner.

When to use

Use when you need to merge two same-shape tuples by combining each position independently, such as summing counters or concatenating strings.

Example (Combining tuple elements)

import { Number, String, Tuple } from "effect"

const C = Tuple.makeCombiner<readonly [number, string]>([
  Number.ReducerSum,
  String.ReducerConcat
])

const result = C.combine([1, "hello"], [2, " world"])
console.log(result) // [3, "hello world"]

See

• makeReducer – like makeCombiner but with an initial value

Signature

declare const makeCombiner: <A extends ReadonlyArray<unknown>>(combiners: { readonly [K in keyof A]: Combiner.Combiner<A[K]>; }) => Combiner.Combiner<A>
