Adding "using library X or language Y" helps in discovering the content during future searches. It also drives people to checkout the code to see if some parts are reusable. There is nothing wrong with mentioning the language and I'm happy to see submissions for other languages and frameworks also mention this these days (Go submissions are really interesting). It helps discover use cases that you might not have thought possible in that language or framework. Compiling prolog to abstract code and running it on a VM written in Rust? Yeah its probably close to the language's target use cases of Rust but it lets people see if such functionality is reusable as a library (in this case found out its not) and how its implemented. I don't know what's with all the Rust hate these days. It's just another language nothing to get fired up about a tag line appended to the title.
