In Rust, interfaces are called traits.cite-ref-5[4] In Rust, structs do not have methods, but instead implement traits which declare methods that the struct implements.

trait Pet {

fn speak(&self);

}

struct Dog<'a> {

name: &'a str

}

impl<'a> Dog<'a> {

fn new(name: &'a str) -> Self {

Dog { name }

}

impl Pet<'a> for Dog<'a> {

fn speak(&self) {

println!("{} says 'Woof!'", self.name);

}
