However, there are some important features that WinSock just doesn’t expose. […]

Rust’s current async ecosystem is built atop a particularly cursed concept. It’s an unstable, undocumented Windows feature. It’s the lynchpin of not only the Rust ecosystem, but the JavaScript one as well. It’s controversial. It’s efficient. […] Without it, it’s unlikely that the async ecosystem would exist in its current form. It’s called \Device\Afd, and I’m tired of no one talking about it.

So I've been writing an allocator. A difficult task and in Rust it is currently a dream to write.

The patterns I'm on about are small quick scopes to get a mutable reference and store or read data.

pub fn some_func(&mut self, s: &[u8]) {
    // Mutable borrow 1 and write
    {
        let writable = &mut self.buf[..8];

        writable[..8].copy_from_slice();
    }

    // Mutable borrow 2 and write
    {
        let writable = &mut self.buf[8..16];

        writable[8..16].copy_from_slice();
    }

    // And so on . . .
}

No other language feels like this. No other language is so precise on reads and writes always taking a length or the length can be obtained from the type (such as a slice).

Writing to different parts of a buffer and selecting parts of like this feels amazing. For writing an allocator i can just make array's and then write any bytes to them and just read them back and cast them about.

So much better than just using raw pointers, and safer as sizes are usually know with slices.

Anyway i just love Rust and this was an excuse to share my love of Rust <3

I aimed to keep it in line with the "demonstration of the Rust ecosystem" goal, so it can also be a great introduction to Rust for beginners who are looking for a fun project to work on. It's not perfect, but that's part of the fun! It leaves room for potential language extensions (to make the AWK clone more complete) and optimizations up to the reader as a follow-up.

An interesting article that lays out a problem and goes through a few different solutions, some of which I haven't thought about much before.

I'm working on a video game in Rust, and I'm running into this kind of modelling problem when it comes to keeping track of the game state. So far I've refactored something that resembles Approach 5 into something that looks more like Approach 3. As I get more confident about the final shape of the data, it (seemingly) becomes a better idea to represent it in a more structured way.
