Struct task_group::TaskManager[][src]

pub struct TaskManager<E> { /* fields omitted */ }

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.
