Fiber

import { Fiber } from "destack:async";

Cooperative execution on the current Worker.

A fiber handle names one parked or running execution for wake delivery.
Handles are plain identities: copying one never copies the execution.

export struct Fiber {
    static current(): Fiber;
    static park<T>(): T;
    wake<T>(value: T): void;
    static spawn(body: () => void): void;
}

Members

static current(): Fiber

Return the currently executing fiber.

static park<T>(): T

Park the current fiber until one wake delivers a value.

wake<T>(value: T): void

Deliver one wake value to this fiber.

A wake sent before the target parks is buffered for its next park.

static spawn(body: () => void): void

Queue one thunk to run on a fresh fiber.
