Struct TaskGroup

pub struct TaskGroup<E> { /* private fields */ }

A TaskGroup is used to spawn a collection of tasks. The collection has two properties:

• if any task returns an error or panicks, all tasks are terminated.
• if the TaskManager returned by TaskGroup::new is dropped, all tasks are terminated.

Implementations

impl<E: Send + 'static> TaskGroup<E>

pub fn new() -> (Self, TaskManager<E>)

pub fn spawn( &self, name: impl AsRef<str>, f: impl Future<Output = Result<(), E>> + Send + 'static, ) -> impl Future<Output = Result<(), SpawnError>> + '_

pub fn spawn_on( &self, name: impl AsRef<str>, runtime: Handle, f: impl Future<Output = Result<(), E>> + Send + 'static, ) -> impl Future<Output = Result<(), SpawnError>> + '_

pub fn spawn_local( &self, name: impl AsRef<str>, f: impl Future<Output = Result<(), E>> + 'static, ) -> impl Future<Output = Result<(), SpawnError>> + '_

pub fn is_closed(&self) -> bool

Returns true if the task group has been shut down.

Trait Implementations

impl<E> Clone for TaskGroup<E>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)
