effect/src/internal/hashMap/keySet.ts

The missing standard library for TypeScript, for writing production-grade software.

import type { HashMap } from "../../HashMap.js"
import type { HashSet } from "../../HashSet.js"
import { makeImpl } from "../hashSet.js"

/** @internal */
export function keySet<K, V>(self: HashMap<K, V>): HashSet<K> {
  return makeImpl(self)
}
