//! A runtime implementation that runs everything on the current thread. //! //! [`current_thread::Runtime`][rt] is similar to the primary //! [`Runtime`][concurrent-rt] except that it runs all components on the current //! thread instead of using a thread pool. This means that it is able to spawn //! futures that do not implement `Send`. //! //! Same as the default [`Runtime`][concurrent-rt], the //! [`current_thread::Runtime`][rt] includes: //! //! * A [reactor] to drive I/O resources. //! * An [executor] to execute tasks that use these I/O resources. //! * A [timer] for scheduling work to run after a set period of time. //! //! Note that [`current_thread::Runtime`][rt] does not implement `Send` itself //! and cannot be safely moved to other threads. //! //! # Spawning from other threads //! //! While [`current_thread::Runtime`][rt] does not implement `Send` and cannot //! safely be moved to other threads, it provides a `Handle` that can be sent //! to other threads and allows to spawn new tasks from there. //! //! For example: //! //! ``` //! # extern crate tokio; //! # extern crate futures; //! use tokio::runtime::current_thread::Runtime; //! use tokio::prelude::*; //! use std::thread; //! //! # fn main() { //! let mut runtime = Runtime::new().unwrap(); //! let handle = runtime.handle(); //! //! thread::spawn(move || { //! handle.spawn(future::ok(())); //! }).join().unwrap(); //! //! # /* //! runtime.run().unwrap(); //! # */ //! # } //! ``` //! //! # Examples //! //! Creating a new `Runtime` and running a future `f` until its completion and //! returning its result. //! //! ``` //! use tokio::runtime::current_thread::Runtime; //! use tokio::prelude::*; //! //! let mut runtime = Runtime::new().unwrap(); //! //! // Use the runtime... //! // runtime.block_on(f); // where f is a future //! ``` //! //!
