Yes, it is that simple. In Rust if you have a structure Person and you want to allow testing equality between instances, you just add that bit of code before the struct definition as follows:

#[derive(PartialEq, Eq)]
struct Person {
    name: String,
    age: u32,
}

In Rust, PartialEq and Eq are traits, which are similar to interfaces in Java. Manually implementing the PartialEq trait in this example would be writing code that returns something like a.name == b.name && a.age == b.age. This is pretty simple but with large data structures it can be a lot of boilerplate.

There also exist other traits such as Clone to allow creating a copy of an instance, Debug for getting a string representation of an object, and PartialOrd and Ord for providing an ordering. Each of these traits can be automatically implemented for a struct by adding #[derive(PartialEq, Eq, Clone, Debug, PartialOrd, Ord)] before it.

Rusty as in the Rust programming language.

Nice

I think this happens because people believe that ad blockers are “too good to be true”. That was what I first thought when first getting an ad blocker, that there was going to be some kind of “catch” like slowing down websites, making them less functional or being malicious. But it turns out they actually improve performance, rarely affect functionality and are even recommended by the FBI because they protect against malicious advertising.

Congrats! As a Linux user of nearly 6 years, I hope you feel welcome here.

It’s really nice how you can now iterate over a boxed slice using for x in &y rather than being forced to use for x in y.iter().

Well said. Privacy shouldn’t be thought of as “all or nothing” but instead as a spectrum, because being completely private is practically impossible for most people and that mentality can lead you to not trying at all.
