Rust Programming By Example

Creating the new project

Let's start by creating a new binary project, as usual:

cargo new --bin ftp-server

We'll add the following dependencies in the Cargo.toml file:

[dependencies]
bytes = "^0.4.5"
tokio-core = "^0.1.10"
tokio-io = "^0.1.3"

[dependencies.futures-await]
git = "https://github.com/alexcrichton/futures-await"

As you can see here, we specify a dependency via a Git URL. This dependency is using nightly-only features, so make sure you're using the nightly compiler by running this command:

rustup default nightly

Let's start our main module by adding the required extern crate statements:

#![feature(proc_macro, conservative_impl_trait, generators)]

extern crate bytes;
extern crate futures_await as futures;
extern crate tokio_core; ...
