Module: Tuple

Tuple.makeEquivalence

Creates an Equivalence for tuples by comparing corresponding elements using the provided per-position Equivalences. Two tuples are equivalent when all their corresponding elements are equivalent.

When to use

Use when you need an Equivalence to compare tuples element-by-element.

Details

This is an alias of Equivalence.Tuple.

Example (Comparing tuples for equivalence)

import { Equivalence, Tuple } from "effect"

const eq = Tuple.makeEquivalence([
  Equivalence.strictEqual<string>(),
  Equivalence.strictEqual<number>()
])

console.log(eq(["Alice", 30], ["Alice", 30])) // true
console.log(eq(["Alice", 30], ["Bob", 30]))   // false
