Example:

code:

    // Consume a list, and return the same list with a new element at its front
    fn prepend(self, elem: u32) -> List {
        // `Cons` also has type List
        Cons(elem, Box::new(self))
    }

"Consume"? Really? I see the code they put there, and for what that does, in my experience most people would just say "takes". Sure, I can maybe accept that "consume" could possibly maybe not quite mean what they use it for here, but for most people in programming (?) "consume" has mutable or destructive connotations, like sucking data from a stream for processing, making it inaccessible for other processors of data from the same stream; it is "consumed" like food and cannot be consumed like food again.
