At its core, OOP is just commingling data and operations, whereas FP is separating data from operations on data. I’m not an expert at Haskell (I cut my FP teeth on Lisp), but that’s essentially what typeclasses look like to me.
The Rust book has a section on OOP, and the main thing to remember is that Rust solves OOP through composition instead of inheritance. Rust doesn’t have inheritance in any meaningful way, but it can solve problems in a similar way as classical OOP.
traits aren’t oop. they’re closer to haskell’s typeclasses than anything else
