Struct task_group::TaskManager
source · [−]pub struct TaskManager<E> { /* private fields */ }
Expand description
A TaskManager is used to manage a collection of tasks. There are two things you can do with it:
- TaskManager impls Future, so you can poll or await on it. It will be
Ready when all tasks return Ok(()) and the associated
TaskGroup
is dropped (so no more tasks can be created), or when any task panicks or returns an Err(E). - When a TaskManager is dropped, all tasks it contains are canceled
(terminated). So, if you use a combinator like
tokio::time::timeout(duration, task_manager).await
, all tasks will be terminated if the timeout occurs.
