Many people think of Rust primarily as a systems programming language focused on memory safety and high performance. All that is true, but there’s much more to the story. Rust is one of the best languages out there for writing strongly typed code: code that takes advantage of type level features to ensure certain classes of bugs cannot happen.

But Rust isn’t magic. Simply using a programming language does not bestow strong typing upon the code. You need to intentionally opt-in to using these features to get their full benefit.

In this talk, we’ll go through some real-life examples of using Rust features like traits, newtype wrappers, generics, and macros for creating financial software. We’ll look at how regular application code can benefit from the features Rust provides.

On top of that, we’ll see how the amazing serde library provides great data marshaling guarantees, and how we can leverage WASM compilation to get these benefits outside the server too.
