This is an hands-on talk, showing a journey from code with a lot of syntactic sugar to plain, veeery explicit Rust code.

Rust allows for a lot of syntactic sugar, that makes it a pleasure to write. It is sometimes hard, however, to look behind the curtain and see what the compiler is really doing with our code. "It is good to know what these conveniences are, to avoid being mystified by what's going on under the hood... the less magical thinking we have of the world, the better." (Tshepang Lekhonkhobe). In this hands-on talk, we will go from code with a lot of syntactic sugar to extremely verbose Rust code.

We will use a little tool called cargo-inspect, which was built for teaching Rust internals. The goal is to make the compiler more approachable to mere mortals.

Rust is a big language and it gets bigger every day. Many beginners ask: "What is idiomatic Rust?". This talk will highlight simple tips to make your Rust code more elegant and concise, and introduce you to my peer-reviewed collection of articles/talks/repos for writing idiomatic Rust code.

Coming from dynamic languages like Python, JavaScript or Ruby, many Rust beginners are missing some guidelines on how to write elegant and concise Rust code. For this purpose, I started a project called "Idiomatic Rust", which is a peer-reviewed collection of articles/talks/repos which teach the essence of good Rust.

In this talk I will introduce the project and show you some quick tips on how to make your Rust code more idiomatic. I will cover error handling (e.g. Option to Result conversions, the failure crate), efficiently working with (built-in) traits, and some more.
