            How much overhead do integer type casts cause in Rust?
            Asked 2021-May-19 at 14:31

            In short:

            If I repeatedly multiply two u8 values and the result can overflow u8's value range, is it more efficient (considering both memory usage and speed) to just use u16 values from the start instead or cast the values to u16s always before the multiplication to prevent overflow?

            The whole story:

            I'm writing a Rust+Wasm program where I have a grid of cells that I pass into JavaScript as a raw pointer to an array (very much like in the Rust and WebAssembly tutorial). The grid cannot ever be larger than 250 x 250 cells in size, so I have the properties width and height for the grid as u8s.

            So, as a simplified example:

            ...

            ANSWER

            Answered 2021-May-19 at 14:30

            Absolutely none for u8 -> u16 which appears to be the gist of your question.

            It is important that it is macro-pessimization, and you mentioning it in your question won't stop me from repeating the common answers that such questions get. You want sensible choice? Use usize for container sizes, as simple as that. There's absolutely no reason to ever limit the size artificially because there's nothing saved, if anything, there's a lot of things being lost.

            1. Your code is unreadable, you even said so yourself.
            2. Your code theoretically may introduce overhead on CPU, for the first time width is read, it is irrelevant, but it may happen, because CPU register size is usize, not u8 or u16, and it may or may not have to bitshift that byte to properly write it into the register, would've been so much easier for it to just read usize which is its natural register size and already properly aligned in memory.
            3. "The grid cannot ever be larger than 250 x 250" Oh yeah? What stops me from inputting 251u8? You will have to write code that validates that anyway if you wanted to enforce that.
            4. Now, why does it stop me from inputting 257usize, 1456usize... Nusize?
            5. Your time is spent on bikeshedding instead of things that matter. I imagine our goal is usually to get things done in least amount of time possible, not maximum.

            General advice: do not optimize container wrappers, optimize the data inside them, that's the sensible choice in any project no matter the scale.

            Besides, what kind of "optimization" is it to limit the maximum size of a Grid? You may not want a Grid bigger than 250x250, but someone else might, and now your code is unusable for no real reason. Someone else might be you, going back to your project 5 months down the line, and cursing your past self while you have to refactor the entire thing just to copy paste it into another project where you want 2500 x 2500 grid for something completely unrelated.

            Lets briefly focus on Grid versus Vec for a bit. How many Grids do you plan to have? I imagine only one, or at most, a dozen. But how many Cell's will there be? Thousands.

            Think of what purpose there is of saving few bytes on Grid, versus few bytes on Cell, the generalization can almost universally boil down to O(1) vs O(n) of bytes saved when it comes to data structures like this.

            When it comes to heavy data processing, you may end up having hundreds of Vec holding potentially hundreds of millions of elements. You should focus on the millions here. That's one of the many reason why Rust Vec itself is just, arbitrarily, 3 usizes. And I'm not aware of any projects that were worried about the fact that Vec stores its length and capacity as usize.

            Above all else, remember: Premature pessimization is root of all evil.

            This might be not the most helpful answer, but the answer is you currently can't - there is an open issue on wasm-bindgen repo tracking future support for debugging but it's not yet supported: https://github.com/rustwasm/wasm-bindgen/issues/2389

            Note that even when it will be, you'll need to use browser DevTools not CodeLLDB for WebAssembly debugging, since you need a JavaScript-capable environment.

            Rust referencing data owned by the current function error for Vec
            Asked 2021-Feb-08 at 11:28

            I am writing code to parse CLI arguments and am stuck on quite a common Rust error.

            What change (ideally without needing to assign everything to individual let variables, do I need to make to fix the compilation error?

            I have been looking at a lot of similar posts as well as re-reaeding the chapter on Ownership in the rust book. However I haven't found a solution to my specific situation.

            When match gives Ok(Config::WorldDef { ... dead_char: Some(&d), alive_char: Some(&a), } the two last references are slices from Strings owned by args_vec (accessed via args_slice).

            When the function exits, args_vec does not exist any more, thus the references in the result would be dangling if Rust didn't complain.

            I suggest that you store Strings instead of &str in the dead_char and alive_char member; this way, the result could take ownership of these to strings from args_vec. By the way, if you do that, I'm not certain args_slice is useful; I think you can just consume args_vec in the match statement because it won't be used afterwards.

            In the definition of new-timer, you're trying to get the grd field of cv.

            And although cv is an instance of the class new-canvas%, its type does not include that field. You need to create a new Class type for new-canvas%. By convention, it should be a capitalized version like New-Canvas%.

            Your problem is how you update the cells. The rules are:

            • a live cell dies if it doesn't have 2 or 3 live neighboure;
            • a dead cell comes alive if it has 3 live neighbours.

            That means that you must consider the current state of the cell to determine its next state, but your code doesn't do that. (It also means that it is enough to count the live neighbours.)

            With the rules above, your update code should look like this:

            I have gone through the tutorial for the Rust Game of Life and have a working game in a web browser, but it only works from the demo web server that comes bundled with it. I can start the server with npm start and it runs the webpack-dev-server on port 8080. When I access the site through that port, it works fine. However, if I try to copy the site to a web server like Apache, it does not load correctly. The error I am currently getting from it is:

            The www and pkg folders contain the source files you need, but you do not have a static site yet. The create-wasm-app template uses Webpack, so you need to build the final output by running npm run build in the www folder. This will create a subfolder named dist which contains the actual static files that can be placed on your web server.

            You are probably facing with a submodule.
            Your www folder is pointing to another git repository.

            Please check in Github, if beside the folder name you have an hash, something like: www @ a773f5e.

            If this is correct, you should have also a file named .gitmodules in the root of the project.

            You can initialize and clone the submobule repository with the command: git submodule update --init

            Edit

            This is a gitlink.

            Typing git ls-tree HEAD www you should see the special mode 160000 at the very left. It is recorded from git as a submodule, but it isn't.

            To recover you need to:

            1. remove from the index the gitlink: git rm --cached www
              This command won't delete your files or your changes from the disk, just from the git's working index.
            2. delete the .git folder: rm -fr www/.git
            3. add the www folder to the index: git add www
            4. commit and push

            Now your www folder should act as a normal folder.
