Today we’re talking about Rust traits . As you might’ve guessed from the title, we will not be talking about them positively. Woah woah, hang on, put down your pitchfork. A local maximum is still a maximum, I love traits as much as anyone.

Traits are one of the few programming language concepts beloved enough to earn multiple names. You might have heard about typeclasses in Haskell or protocols in Swift. Heck, if the teacher’s not watching, even interfaces can be considered a kind of trait. Elm famously left out traits, and it was so requested it spawned an FAQ explaining their absence.
