Processing Real-world Data Efficiently with Rust

Server Basics

Explore building basic servers in Rust using the Warp framework to serve data through web applications. Learn how to define routes, handle HTTP methods, work with request bodies, and inspect headers. Understand routing, multipart paths, and how to return JSON responses. Gain the skills to create data servers suitable for remote access and web services.

We'll cover the following...

Having the data on your machine and elaborating on it is just one part of the modern data endeavor. Data should, in fact, be available remotely through servers and web services.

The basics of web applications in Rust

Rust has many different web frameworks that can be used to spin up a server. There’s not a single preferred choice, nor is there a full-fledged solution. We can’t replace Laravel, Rails, or Django with a Rust equivalent, but there are lighter frameworks equivalent to Flask or Sinatra.

For this course, we’ll explore Warp, which is like a more robust version of Express.js.

First, let’s prepare our Cargo.toml, like so:

[dependencies]
warp = "0.3.2"

Then, let’s spin up a server:

Rust 1.40.0
use warp::Filter;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    server_setup!(3); // Needed for this playground to work
    let routes = warp::any().map(|| "Hello, World!");
    println!("Server started on: http://127.0.0.1:3030");
    warp::serve(routes).run(([127, 0, 0, 1], 3030)).await;
    Ok(())
}
