Trait Executor

pub trait Executor {
    // Required methods
    fn block_on(&self, f: Pin<Box<dyn Future<Output = ()>>>);
    fn spawn(
        &self,
        f: Pin<Box<dyn Future<Output = ()> + Send>>,
    ) -> Box<dyn Task>;

    // Provided method
    fn spawn_local(
        &self,
        f: Pin<Box<dyn Future<Output = ()>>>,
    ) -> Result<Box<dyn Task>, LocalExecutorError> { ... }
}

A common interface for spawning futures on top of an executor

Required Methods

fn block_on(&self, f: Pin<Box<dyn Future<Output = ()>>>)

Block on a future until completion

fn spawn(&self, f: Pin<Box<dyn Future<Output = ()> + Send>>) -> Box<dyn Task>

Spawn a future and return a handle to track its completion.

Provided Methods

fn spawn_local( &self, f: Pin<Box<dyn Future<Output = ()>>>, ) -> Result<Box<dyn Task>, LocalExecutorError>

Spawn a non-Send future on the current thread and return a handle to track its completion.
