Trait Executor

pub trait Executor {
    type Task<T>: Future<Output = T>
       where T: 'static;

    // Required methods
    fn spawn<F>(&self, future: F) -> Self::Task<F::Output>
       where F: Future + Send + 'static,
             F::Output: Send + 'static;
    fn detach<T>(&self, task: Self::Task<T>);
}

An executor which futures can be spawned on.

Required Associated Types

type Task<T>: Future<Output = T> where T: 'static

A task which completes with the output of a future.

Taskss have abort-on-drop semantics.

Required Methods

fn spawn<F>(&self, future: F) -> Self::Task<F::Output>

where F: Future + Send + 'static, F::Output: Send + 'static,

Spawns the given future on this executor, returning a Task for the task.

fn detach<T>(&self, task: Self::Task<T>)

Detaches the given task so that it can run independely in the background.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
