How to showcase Rust

Hey everyone,

im working in a project where we process a lot of files and we use Java / Spring for the whole project. My question is what is the best showcase option for rust against Java / Spring

What part of Spring are you using? Spring Boot with RestController or something else? Spring is a big framework with a lot of parts so it would help if you can be specific.

(Edit: We use a lot of Spring Boot at work, but we have started enhancing our stuff with serverless Rust).
