Package: effect
Module: Either

Either.all

Takes a structure of Eithers and returns an Either of values with the same structure.

• If a tuple is supplied, then the returned Either will contain a tuple with the same length.
• If a struct is supplied, then the returned Either will contain a struct with the same keys.
• If an iterable is supplied, then the returned Either will contain an array.

Example

import * as assert from "node:assert"
import { Either } from "effect"

assert.deepStrictEqual(Either.all([Either.right(1), Either.right(2)]), Either.right([1, 2]))
assert.deepStrictEqual(Either.all({ right: Either.right(1), b: Either.right("hello") }), Either.right({ right: 1, b: "hello" }))
assert.deepStrictEqual(Either.all({ right: Either.right(1), b: Either.left("error") }), Either.left("error"))

Signature

declare const all: <const I extends Iterable<Either<any, any>> | Record<string, Either<any, any>>>(input: I) => [I] extends [ReadonlyArray<Either<any, any>>] ? Either<{ -readonly [K in keyof I]: [I[K]] extends [Either<infer A, any>] ? A : never; }, I[number] extends never ? never : [I[number]] extends [Either<any, infer E>] ?
