Struct Inner 

struct Inner {
    tasks: Mutex<HashMap<usize, TaskHandler>>,
    next_id: AtomicUsize,
    executor: Executor,
}

Shared state of a TaskGroup. Held behind an Arc so each task can keep a Weak reference back to the group and remove itself on completion, without forcing callers to wrap the group in an Arc.

Fields

tasks: Mutex<HashMap<usize, TaskHandler>>

next_id: AtomicUsize

executor: Executor

Implementations

impl Inner

fn remove(&self, id: usize) -> Option<TaskHandler>

Removes a task by id, returning its handler if still present.
