In his talk at EuroRust 2024, Niklas Korz discusses the integration of runtime scripting languages into Rust applications, highlighting the benefits of allowing dynamic scripting for prototyping and user extensions. He explores various scripting solutions, including WebAssembly, Ry, Mune, Lua, Python, and JavaScript, with a focus on using Deno for embedding JavaScript into Rust applications. Korz emphasizes the importance of sandboxing and memory safety, and provides practical examples of how to expose Rust functions to user scripts, along with resources for further learning.
