<T>(schema: Schema<T>): Equivalence.Equivalence<T>

Derives an Equivalence from a schema. Two values are considered equal when every field (and nested field) compares equal according to the schema structure.

Example (Comparing structs)

import { Schema } from "effect"

const eq = Schema.toEquivalence(Schema.Struct({ id: Schema.Number, name: Schema.String }))

console.log(eq({ id: 1, name: "Alice" }, { id: 1, name: "Alice" })) // true
console.log(eq({ id: 1, name: "Alice" }, { id: 2, name: "Alice" })) // false
