Trait Executor

pub trait Executor: Sized {
    // Required methods
    fn new() -> Result<Self, Error>
       where Self: Sized;
    fn spawn(&self, future: impl Future<Output = ()> + MaybeSend + 'static);

    // Provided method
    fn enter<R>(&self, f: impl FnOnce() -> R) -> R { ... }
}

A type that can run futures.

Required Methods

fn new() -> Result<Self, Error>

where Self: Sized,

Creates a new Executor.

fn spawn(&self, future: impl Future<Output = ()> + MaybeSend + 'static)

Spawns a future in the Executor.

Provided Methods

fn enter<R>(&self, f: impl FnOnce() -> R) -> R

Runs the given closure inside the Executor.

Some executors, like tokio, require some global state to be in place before creating futures. This method can be leveraged to set up this global state, call a function, restore the state, and obtain the result of the call.

Object Safety

This trait is not object safe.
