[–] TehPers@beehaw.org 9 points 11 months ago (1 child) This doesn't represent the mutual exclusivity through the type system (which is what the article is all about). I love clap and I use it a lot, but the only way to represent the exclusivity through the type system in Rust is through an enum. permalink fedilink source parent hideshow 2 child comments replies: [–] ExFed@programming.dev 5 points 11 months ago Agreed. As nice as clap is, it's not a combinator.
