pub trait Task<T>: Future<Output = T> + Send {
    // Required method
    fn cancel<'life0, 'async_trait>(
        &'life0 mut self,
    ) -> Pin<Box<dyn Future<Output = Option<T>> + 'async_trait>>

Expand description

A common interface to wait for a Task completion, let it run n the background or cancel it.

Required Methods§

Source

fn cancel<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Option<T>> + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Cancels the task and waits for it to stop running.

Returns the task’s output if it was completed just before it got canceled, or None if it didn’t complete.
