TaskScope

1 min read

Import: import system.task;

Read the usage guide for examples and common tasks. This reference lists the public declarations for this part of the library. See Reading API signatures for parameter and result notation.

TaskScope

Owns async and parallel children; its enclosing Task.scope joins every child before returning.

public class TaskScope<E>

token

The inherited cancellation token for this scope and its children.

public get token(): CancellationToken

cancel

Requests cooperative cancellation; completion still waits for child cleanup.

public fun cancel(): void

spawn

Schedules a child immediately and retains it even if its result handle is discarded.

public fun spawn<T>(body: fun(): Future<Result<T, E>>): TaskHandle<T, E>

spawn_parallel

Schedules CPU work on the runtime's shared worker threads and retains structured ownership.

public fun spawn_parallel<T: shared>(body: fun(): T): TaskHandle<T, E>

spawn_on

Schedules CPU work on an explicit reusable pool while retaining structured ownership.

public fun spawn_on<T: shared>(pool: TaskPool, body: fun(): T): TaskHandle<T, E>
