Package: effect
Module: FiberSet

FiberSet.runtimePromise

Captures a Runtime and returns a Promise-based runner that forks effects into the FiberSet.

When to use

Use when you need to bridge effects to Promise values while still tracking their fibers in a FiberSet.

Details

The returned run function returns a Promise for each effect result.

Example (Running effects as promises)

import { Effect, FiberSet } from "effect"

const program = Effect.gen(function*() {
  const set = yield* FiberSet.make()
  const runPromise = yield* FiberSet.runtimePromise(set)()

  // Run effects as promises
  const promise1 = runPromise(Effect.succeed("hello"))
  const promise2 = runPromise(Effect.succeed("world"))

  const result1 = yield* Effect.promise(() => promise1)
  const result2 = yield* Effect.promise(() => promise2)

  console.log(result1, result2) // "hello" "world"
})
