Predicate.isReadonlyRecord

A refinement that checks if a value is a readonly record (i.e., a plain object). This check returns false for arrays, null, and functions.

This is an alias for isRecord.

Example

import * as assert from "node:assert"
import { isReadonlyRecord } from "effect/Predicate"

assert.strictEqual(isReadonlyRecord({}), true)
assert.strictEqual(isReadonlyRecord({ a: 1 }), true)

assert.strictEqual(isReadonlyRecord([]), false)
assert.strictEqual(isReadonlyRecord(null), false)

Signature

declare const isReadonlyRecord: (input: unknown) => input is { readonly [x: string | symbol]: unknown; }
