TaskScope

import { TaskScope } from "destack:async";

Structured owner of spawned tasks.

Asynchronous disposal waits for every child before it completes.
Cancellation requests are delivered cooperatively at cancellable asynchronous operations.

export struct TaskScope {
    static open(): TaskScope;
    spawn<T: Copy>(body: () => Task<T>): Task<T>;
    cancel(): void;
    async asyncDispose(): Promise<void>;
    drop(): void;
}
