Struct Task

Source
pub struct Task { /* private fields */ }
Expand description

Holds state of a single top-level task that can be run by an executor

Implementations§

Source§

impl Task

Source

pub fn spawn(future: impl Future<Output = ()> + 'static)

Spawns a new Task that will run on the same executor as the current Task

§Panics

This function panics if it is called from a context outside an executor or an async function.
