Struct Group

Source

pub struct Group(/* private fields */);

Expand description

A group of tasks that share a common fate. Any tasks that are spawned onto the group will be aborted if any task fails or if the group is aborted.

The group is also aborted if the group itself is dropped.

Implementations§

Source §

impl Group

Source

pub fn spawn<F, T, E>(&self, fut: F)
where F: Future<Output = Result<T, E>> + Send + 'static,

Spawn a new task onto this group. If the task fails, the group is aborted. If tasks are spawned onto an already stopped group, they are simply never run.

Source

pub fn fail(&self)

Fail the group. This is equivalent to spawning a task that immediately fails.
