> you can highlight a binding if it’s mutable or style an enum/struct differently
Wow! That is an incredibly good reason. Thank you very much for telling me something I didn’t know. :)
UPDATE: I've added a paragraph talking about the ability of rust-analyzer. Thank you again!
Another pretty common application is to color unused bindings with a slightly faded-out color. So for e.g. with the TypeScript LSP, up at the top of the file you can instantly tell what imports are redundant because they're colored differently.
I love this in xcode / swift. Where classes and structs have a different colors between local classes and external classes (from a lib).
Its surprisingly useful to know if you’re working with a entity that you made.
