I understand that the macro only affects compile time but I’m talking about the extra function that’s included in the resulting source code when the macro is expanded during compile. Based on other feedback, it looks like the unused function is optimized away.
This was a great post, but is the last state of the macro actually bad for performance in any way? I get that it’s ugly (and we should only choose to make code less readable like this when there’s actually an issue) but is it worse for runtime performance?
I prefer to encapsulate a mutable reference to the instance in a scope.
let post_form = {
let mut post_form = PostInsertForm::new(
// your constructor arguments
);
post_form.some_mutating_method(
// mutation arguments
);
post_form
};
This way you’re left with an immutable instance and you encapsulate all of the logic needed to setup the instance in one place.

Eternal Sunshine of the Spotless Mind
I’ve literally sat down in city centers surrounded by buildings. It’s an amazing feeling.
I wish I could experience that. I wish our sci-fi fairytales of space travel were happening now. Alas, I must simply exist in a life lived better than a king of old, living longer than our ancestors, with food untasted by the billions before us, and all while I fly around in space within Eve Online while watching Star Trek. Life is great, but it’s so easy to want it to be just that much better.
Someone just suggested to me that I should be putting my chocolate bars in the freezer first. I’ve never heard of this, but apparently it’s a thing that I’ve been missing out on for a while.
So I guess I’m the one who can’t believe that I don’t do it.
I loved both of these games as a kid.
Oh, okay. Thank you for clarifying. So doesn’t that mean we should never have a compiler written in the same language that it compiles? Why would we ever choose to make the mistake of using the same language? Is it ever not a mistake?
Why would a Rust compiler written in C be more trustworthy than one written in Rust?
I’m still lost on why they’re doing it.
It just felt so cliche, that the crazy discovery they make is that the strange stuff is alive. The writers couldn’t make it sentient because then they’d need to explain why it’s just like the Great Lake but different from the Great Lake. It just exists and Star Fleet happens to be the only ones who know about it.
lol, I love that you’re conflating the creator having the budget to make the show more in-line with his original vision with someone else making a lousy change for no clear reason. It’s a nice knee-slapper of a comment you have right there. Good luck with it.
Who wanted a visual reboot of the Klingons?
Discovery had so many problems for me: ship flies on magic mushrooms, her mom basically doesn’t care about her anymore by the end of it - the show-starting plot line, and the Klingons look like sweaty orcs.
The idea that someone would introduce the verbiage “garbage collection” in the context of Rust is crazy to me. I hope they change that to “file cleanup” or… anything else.
Who is writing SQL in the terminal?
AI is surprisingly helpful with providing a starting point. When you want a helloworld app, an example of how to use some part of a crate, or a code snippet showing how to take what you have and do something unusual with it, AI is super useful.
I would love to be able to get the same quality of AI locally as I do from ChatGPT. If that’s possible, please let me know. I’ve got two 3090s ready to go.
But for now, I’m just enjoying the fact that ChatGPT is free. Once they put up a pay wall, it’s back to suffering (or maybe/probably trying out some open-source models).
The aliens haven’t yet consumed our planet in this timeline. Consider yourself lucky.
