    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.

      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

    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  2 года назад +5

    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!

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

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

      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

      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heard good things about The Rust Programming Language by Steve Klabnik and Carol Nichols, no starch press, but it's outdated (a new edition should be available later next year).
