Import

import { RefBigInt } from "@typed/fx";

Access RefBigInt.make through the imported RefBigInt export. Its declaration below describes the member.

This public exposure is a re-export. Its import path is supported; declaration documentation is shared with the other public exposures below.

Signatures

export declare function make<E = never, R = never>(initial: bigint | Effect.Effect<bigint, E, R> | Fx.Fx<bigint, E, R>, eq?: Equivalence<bigint>): Effect.Effect<RefBigInt<E>, never, R | Scope.Scope>;

Why

Creates big int state with equality suited to that Effect data type, so unchanged values do not produce redundant pushed updates.

Ownership and lifetime

The creation Effect requires Scope. It owns initializer acquisition, live source subscriptions, and cleanup; source failures and services stay on reads and pushes.

Examples

import { Effect, BigInt } from "effect"
import * as RefBigInt from "@typed/fx/RefBigInt"

const program = Effect.gen(function* () {
  const value = yield* RefBigInt.make(BigInt.BigInt(123))
  const current = yield* value
  console.log(current) // 123n
})
