Because we're starting to write code in this chapter, you'll need to have certain software in order to compile and run examples:

• I recommend you use the rustup tool, which will keep your Rust instance up to date. If you don't have this tool, you can get it from https://rustup.rs/. When it's installed, run the rustup update command to update the current installation.
• The Rust compiler, at least version 1.31.
• The hyper crate, which we'll use to compile the code, requires the OpenSSL (https://www.openssl.org/) library. The most popular operating systems already include the OpenSSL package and you can follow the manual of your package manager to install it.

You can get the examples shown in this chapter from GitHub at https://github.com/PacktPublishing/Hands-On-Microservices-with-Rust/tree/master/Chapter02.
