Runtime Scripting for Rust Applications

Rust is a statically typed, ahead of time compiled and memory safe programming language. But sometimes, the restrictions Rust puts on us developers can be a hindrance, for example when prototyping new application ideas or when you want your end users to be able to change your application’s runtime behavior. Thankfully, we can embed dynamically typed scripting languages with a lower learning curve into our Rust applications to get the best of both worlds.

In this talk, we will have a look at the scripting languages available to the Rust ecosystem and compare how well they integrate into Rust. Finally, we go through the process of embedding such a scripting runtime, Deno, into a Rust application and investigate how we can expose operations from our host applications to our scripts as well as share state between them.
