Expanding the Tokio project
If you’ve been following Rust in the last month, you’ve probably seen the announcements of the Futures library and the Tokio framework that sits on top of it. There’s been some confusion about how these projects fit together, and what the overall story is shaping up to be.
Today, we’re happy to announce the formation of the Tokio Core Team, as well as an overall plan for the two projects and how they fit together. The team consists of Carl Lerche, Alex Crichton, and myself; more on that below.
An early vision of the I/O stack
There are three primary levels of abstraction in Tokio:
- At the highest level is a service, which is where you write a server application. Following the Finagle model, a service is a simple thing: it’s a function from requests to futures of responses. This simple model is incredibly powerful: it separates the implementation of request processing from the implementation of the underlying protocol, and makes it possible to factor out an ecosystem of middleware. All of this seamlessly support async I/O via futures. Middleware runs the gamut from connection pooling to retry/timeout logic to logging to load balancing – all of which can be written independently from any particular service or protocol. Read Your Server as a Function for the inspiration.
The tokio-service crate provides core trait definitions for services. Servers that can process particular request/response types (like HTTP) are offered as standalone crates. Building an http server is just a matter of writing a function from http requests to futures of http responses.
In the middle are protocols, like HTTP or Mux. Here, too, there is a lot of complexity worth factoring out, both at the transport layer and in the protocol “dispatch” layer. The tokio-proto crate provides re-usable components for building new protocol implementations. We expect for there to be a similar kind of “middleware” ecosystem at these lower levels.
At the lowest level is the event loop, which is where we bridge the OS’s I/O facilities into the world of futures. The tokio-core crate provides a generic event loop for doing async I/O with futures.
In short, we want the Tokio project to be a “one stop shop” for doing futures-based I/O, whether at the highest level of prebuilt protocols, or the lowest level of the core event loop.
In our view, the lowest layers should strive to be zero cost and fully general, allowing them to be used in a large number of contexts. As you go up the stack, getting closer to an actual application, things tend to get more specific and opinionated, and may impose some cost. Futures themselves are a zero-cost and very general abstraction in Rust, and the tokio-core crate imposes very little cost. Particular protocol implementations and middleware, on the other hand, can be more opinionated.
We’ll have a lot more to say about all of these layers (and the ones beneath them, like futures) in the coming weeks on our various blogs. Stay tuned!
A note on project management
We’re following a Rust-like model, starting with a core team that reaches major decisions through a consensus process. At the moment, this process is fairly informal: it plays out on the issue tracker, PRs, and gitter channels. But as the library begins to mature, we plan to move toward an RFC-like process for major changes. We are eager for the Tokio project to truly be a Rust community project. It’s going to have a lot of stakeholders, and we want to make sure those stakeholders have a voice just as we do in the Rust project itself.
As for the core futures library, it remains separate from the Tokio project, in part because we imagine it heading toward ownership by the rust-lang org in the relatively near future. (That’s a possible eventual path for Tokio as well, but the road will be much longer.)
Jumping in
Tokio is an ambitious project, and it’s going to take a strong community to really get it off the ground. Many from the Rust community have already jumped in to contribute, even in these extremely early days; that’s helped us get some of our early-stage integrations going, including curl, tls and redis. We’re also working with Sean McArthur to get a Tokio-integrated Hyper off the ground. If you’re interested in any of this, any other integrations, or the core libraries, we’d love to hear from you!
If you’re coming to RustConf, we’ll see you there, either at the Tokio hack night or at the talk about futures at RustConf itself. Come say hello, and join in the fun!


Deal alert: You can fly round-trip Vancouver to Sydney, Australia for only $680 CAD
by Elana ShepertWhether you’ve ever wanted to watch a troop of kangaroos hop across the outback, or you simply want to enjoy the view from the iconic Sydney Opera house, Australia offers endless things to see and do.
And while the least expensive flights to the popular destination usually cost between $1,050 to $1,650 CAD, Air Canada has dropped its prices on a number of Australia tickets. In fact, prices are roughly half the regular price, and many of the options are direct.
For example, the flight below offers return airfare for under $700 CAD. The flight departs Vancouver on Monday, Mar. 2 and returns on Wednesday, Mar. 18, and both flights are non-stop.
Discover Sydney, Australia
From glistening white-sand beaches to vibrant coral reefs, delectable eateries to endless shopping experiences, there are a number of things to see and do Australia. Of course, the country is famous for its wildlife, and there are a variety of tours that take travellers up close and personal with some of the most fascinating creatures in the world.
You may book your flight here.

Built while just starting to learn Angular 2, I needed something that can be used as boilerplate for a single page app, something that my team can easily use right away. This can serve as boilerplate for a small to medium-sized single-page app with minimal modifications.
My problem with Angular 2 right now is that most of the resources are in TypeScript. I'm going to use Angular, My team can't use TypeScript. We have a deadline.
We're dinosaurs when it comes to javascript so the only cli command is just npm install and my JavaScript is just JavaScript. I don't have anything running on the background. Learn TypeScript when you have the time or you'll be judged accordingly. :P
If you're a designer, you can skip all the javascript files. It's supposed to take care of itself. Just familiarize yourself with the structure.
 All you have to do is copy/paste a component folder and focus on building your component.
Project folder ├─── index.html ├─── package.json ├┬── assets/ │├── css/ │├┬─ images/ ││└─ logo.png │└── js/ ├┬── node_modules/ │└── etc... │ └┬── app/ ├── app.js ├── app.html ├── app.css ├── main.js ├── app.module.js │ ├┬─ utils/ │└─ pipes.js │ │ └┬─ __component/ ├─ __component.js └─ __component.html
Explanation
Files here at the top are self explanatory.
This is our single-page app. It's a typical Angular 2 component. The JS, HTML, and optional CSS are in this folder together with some Angular 2 boilerplate. This is how we'll organize it.
A custom pipe. Pipes are just filters from Angular 1. This is a simple example used throughout our app to capitalize the first letter.
Let's put components in their own subfolder inside app/. Things for this component belong in here, otherwise they go in utils/ like our custom pipe.
Copy/paste this folder and change the file name (use lowercase) and use the same name for the constant (capitalize first letter) inside the script for a new component.
That's it! We'll see how it works in the next section.
