Trait Task

pub trait Task {
    type Ok;
    type Error;
    type Future: Future<Output = Result<Self::Ok, Self::Error>>;

    // Required method
    fn run(&mut self) -> Self::Future;
}

A task produces an asynchronous computation that can be retried if the returned future fails with some error.

Required Associated Types

type Ok

The type of successful values yielded by the task future.

type Error

The type of failures yielded by the task future.

type Future: Future<Output = Result<Self::Ok, Self::Error>>

The future returned when executing this task.

Required Methods

fn run(&mut self) -> Self::Future

Return a future.
