Catching up with async Rust
In December 2023, a minor miracle happened: async fn in traits shipped.
As of Rust 1.39, we already had free-standing async functions:
pub async fn read_hosts () -> eyre:: Result < Vec < u8 >> {
// etc.
}
…and async functions in impl blocks:
impl HostReader {
pub async fn read_hosts ( & self ) -> eyre:: Result < Vec < u8 >>
Printing ASCII cats to the terminal
Now that our development environment is all set up, let’s make something useful!
Creating the catscii crate
From a VS Code window connected to our VM (as we just set up), let’s make a new Rust project:
amos@miles:~$ cargo new catscii
Created binary (application) `catscii` package
And open it in a new VSCode window:
amos@miles:~$ code catscii
Just paying Figma $15/month because nothing else fucking works
My family wasn’t poor by any stretch of the imagination, but I was raised to avoid spending money whenever possible.
I was also taught “it’s a poor craftsman that blames their tools”, which apparently means “take responsibility for your fuckups”, but, to young-me, definitely sounded more like “you don’t deserve nice things”.
I was also taught from an early age that I was born a sinner, incapable of doing good by myself, and that all the earthly things were temptations, sent by the devil to corrupt me (further I guess?) but also temporary, and that I shouldn’t attach myself.
Day 11 (Advent of Code 2022)
It’s a new day, it’s a new advent of code puzzle.
In that one, we have to apparently cosplay as an IBM mainframe and just.. crunch them numbers. This doesn’t look fun, and I can’t think of a clever twist to make it fun, so let’s try to make it short and sweet.
Parsing
Our input looks like this:
Monkey 0 :
Starting items: 79 , 98
Operation new = old
divisible by
true throw to monkey
false throw to monkey
items
new = old +
divisible by
true throw to monkey
false throw to monkey
etc
Day 17 (Advent of Code 2022)
Advent of Code gets harder and harder, and I’m not getting any smarter. Or any more free time. So, in order to close out this series anyway, I’m going to try and port other people’s solutions from “language X” to Rust. That way, they already figured out the hard stuff, and we can just focus on the Rust bits!
Sounds good? Good. Let’s proceed.
Porting poppler to meson
It took a hot minute.
Try several weeks.
Well, yeah. I got to contribute to a bunch of open-source projects in the meantime though, so I’m fairly pleased with it!
- libffi (for static linking)
- cairo (more static linking!)
- proxy-libintl (more static linking!)
- expat (static linking strikes again)
- poppler (for file descriptor stuff not properly gated on Windows, closed in favor of a similar MR)
A static poppler build: the easy way
Efficient game updates
A little while ago, I wrote an article on things that can go wrong when downloading, it listed a series of reasons, from network problems to invalid content to imperfect hardware that may occur when initially installing a game.
This article discusses what methods we can use to upgrade a game to a later version, when an older version has been successfully installed.
A simple ping library, parsing strings into IPv4 address
We’ve just spent a lot of time abstracting over LoadLibrary, but we still have all the gory details of the Win32 ICMP API straight in our main.rs file! That won’t do.
This time will be much quicker, since we already learned about carefully designing an API, hiding the low-level bits and so on.
Let’s add an icmp module to our program. Actually, we’ve been dealing with
an IPAddr all this time, it also sounds like it could use its own package:
Three gamedev surprises
Despite their peaceful appearance, game developers actually lead thrilling lives! Here are three things I learned (or re-learned) about yesterday that I’d like to share with you, in the form of assumptions that revealed false.
VSync is relatively straightforward. Right?
As an obsessive-compulsive, bipolar, perfectionist game dev, getting your game to run smoothly on all kinds of operating systems, graphics cards, and drivers combination is something of a holy grail. Many look for it, but let’s be honest here, it never really turns out as expected.
