Package: effect
Module: Combiner

Combiner.flip

Reverses the argument order of a combiner’s combine method.

When to use

Use when you want the right-hand value to act as the accumulator, or need to reverse a non-commutative combiner such as string concatenation.

Details

Returns a new Combiner where combine(self, that) calls the original combiner as combine(that, self).

Example (Reversing string concatenation)

import { Combiner, String } from "effect"

const Prepend = Combiner.flip(String.ReducerConcat)

console.log(Prepend.combine("a", "b"))
// Output: "ba"
