Task

import { Task } from "destack:async";

Single-consumer asynchronous result on its own fiber.

Awaiting a task blocks the current fiber and moves the result out.
Cancellation requests are delivered cooperatively at cancellable operations.

export class Task<T> {
    static resolve<T>(value: T): Task<T>;
    static spawn<T>(body: () => T): Task<T>;
    static block<T>(task: Task<T>): T;
    cancel(): void;
}

Block the current fiber until a task completes, moving the result out.
