For another example of semantics-aware highlighting for Rust, see Flowistry, which allows you to select an expression in order to highlight all the code that either influences or is influenced by that expression: https://github.com/willcrichton/flowistry

Whoa, that's slick! I wish it were available in Zed. Maybe someday!

Flowistry publishes their underlying rustc plugin as a crate, so all the analysis is already done for you, you'd just need to integrate the output with your editor of choice.

Thanks for sharing this project! That's a really neat idea and would help me a lot with understanding code written by others. It's unfortunate that it's only available for Rust, but it makes sense that the language design really lends itself to this.

Looking at this, I noticed how long it's been since I saw a new IDE feature that really made me more productive at understanding code. The last I can really remember was parameter inlay hints. It's a bummer - both the Jetbrains IDEs and VS Code seem to only focus on AI features I don't want, to the detriment of everything else.
