[−][src]Struct futures::compat::TokioDefaultSpawner

pub struct TokioDefaultSpawner;
[−]

A spawner that delegates to tokio's DefaultExecutor, will panic if used in the context of a task that is not running on tokio's executor.

NOTE The future of this struct in futures is uncertain. It may be deprecated before or soon after the initial 0.3 release and moved to a feature in tokio instead.

Examples

ⓘThis example is not tested
#![feature(async_await, await_macro, futures_api)]
use futures::future::{FutureExt, TryFutureExt};
use futures::spawn;
use futures::compat::TokioDefaultSpawner;

let future03 = async {
    println!("Running on the pool");
    spawn!(async {
        println!("Spawned!");
    }).unwrap();
};

let future01 = future03
    .unit_error() // Make it a TryFuture
    .boxed()  // Make it Unpin
    .compat(TokioDefaultSpawner);

tokio::run(future01);
