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 JoinHandle returned by group is dropped, all tasks are terminated.
