Assigning "Bob" to variable "a" and "Alice" to variable "b" is just evil

@BrandonCharlesHouser Год назад

In VS Code, if you hold alt and then press the up or down arrow it will move the line you are on or your entire selection up or down. It's great for reorganizing switch statements, if else ladders, and just re-organizing code.

@codetothemoon Год назад

ahh didn't know about this, thank you!

@egorsozonov7425 3 месяца назад

It’s not great, it’s terrible. Pressing Alt and arrows at the same time requires you to move your hand very far from the home row! Better editors like Neovim have saner hotkeys as well as a way to reassign them arbitrarily

Hey remember you can use the rust language reference to help under stand the token syntax of a macro!

@codetothemoon Год назад

Agree, it's a great resource!

@jeffg4686 Год назад

Found an interesting syntax today, which is tuple pattern matching, where all elements of the tuple value can become 'wildcard' matches / variables'.

@codetothemoon Год назад

I find this feature super handy, I think it's called "destructuring"!

@jeffg4686 Год назад

@@codetothemoon - yeah, it's destructuring, but never seen it before in this context (matching).

@sparky173j Год назад

Thankyou for this and all your other videos. I usually prefer learning these things from video demos over documentation. I've been procrastinating adding macros to my project. I'll probably mostly be using derive macros, but I think declarative macros will be a good place to start.

@codetothemoon Год назад

Thanks for watching tev. I really enjoy making them, especially when I get comments like this! Declarative macros can be a great place to start (though you don't have to). Will probably be making a custom derive video at some point...

@HyperFocusMarshmallow Год назад

@codetothemoon 9 месяцев назад

@africknchickn_YT Год назад

if you do a similar walkthrough for proc macros, I *will* subscribe. In my experience, building a custom derive is a more common use case that I wish I had the time to learn in detail how to do, as opposed to defining and parsing a new DSL. So (if you're taking votes...) my vote would be for doing a recursive derive of structs and enums! If not, then no worries :) I'll still be around. Cheers dude!

@codetothemoon Год назад

Nice, I've been thinking a lot about a proc macro video. I've found it incredibly challenging to explain those concepts in a concise and digestable way - I think it can be done though! Thanks for watching!

Does anyone know how to implement Stripe and JWT in rust for e-commerce

@codetothemoon Год назад

I second this. I've been mulling a Stripe video for some time, definitely a huge area of interest. For JWT / OAuth in Rust I actually did a video on that several months ago

@artursradionovs9543 Год назад

@@codetothemoon no official docs available. I love Rust a lot, but it takes a lot of time as a beginner to pick this up. My goal is to develop a small Android Native App with Actix as a backend framework, but note sure if I will succeed. Rust really is harder than Java, Python or JS.

@Daveiac Год назад

Is there a way to specify the types of elements to the set? Like what if you were to do set!(1,"2",'3'), would it compile?

@ianakotey Год назад

Nah, compiler would infer their types are different and reject

@codetothemoon Год назад

yeah like Ian mentions, the HashSet itself has to be of a specific type so this wouldn't compile - this isn't related to the macro itself, it would still happen if you tried to do that directly with HashSet::from

@narayanbhat3279 Год назад

shouldn't you first create an empty hashset and then push each of the elements into the set?

@codetothemoon Год назад

That would work too. I'm honestly not sure which approach is more efficient.

@eddex. Год назад

Why did the "thing = 5" variable match the "a arm"? And how can it match "a" when there's no variable called "a"?

@theaiguy_ 8 месяцев назад

That is because a can be anything, 5 included, so it matches.

Usually the general case is named "_", but really can be anything

nit: println takes a string literal, not a slice. One of the hallmarks of a macro is that it can distinguish the two whereas functions can't.

@phenanrithe Год назад

The best I've read is this book: Programming Rust by Jason Orendorff, Jim Blandy, and Leonora F .S. Tindall, O'Reilly. It covers the last 2021 edition, is superbly written and covers all the topics by explaining everything with a good learning curve. I've heard good things about The Rust Programming Language by Steve Klabnik and Carol Nichols, no starch press, but it's outdated (a new edition should be available later next year).

@banocean 6 месяцев назад

Tbh your videos now are kinda let's do thing I can read in the docs/rust book :/

@codetothemoon 6 месяцев назад

thanks for the feedback. I only make videos on topics that are covered in the Rust book if I think i can offer a different approach and explanation that makes it easier to understand, which was the case for this video. Another example would be the one on interior mutability. Maybe I missed the mark on this one!
