import { PromiseCompletionSource } from 'promise-completion-source'

const promiseCompletionSource = new PromiseCompletionSource<Result>()

// This is a promise which can be awaited or passed around as a future
const promise = promiseCompletionSource.promise

promiseCompletionSource.reject(new Error('Some error'))
