I'm a complete noob to any of this, I literally just needed it to run one program over from MACOS to Windows, but I'm not understanding anything that's going on. I've been trying to get this to work for 24 hours now, tried cargo clean like some posts said but that does nothing without cargo.toml as well.

It looks like gifski may also require you to download the ffmpeg libraries and set an environment variable pointing to their location. For details, see:
Or you can download a pre-compiled version of gifski from https://gif.ski/ instead of compiling it yourself.
Interesting, I'll see if I can get that to work. As for the gifski stuff, I've already got everything ffmpeg-wise, as I do understand enough of that; what drew me here is that some of the features, namely the ability to use mp4s, required a cargo installation as opposed to the painstaking process of manually cutting videos into frames with ffmpeg and putting them together again.
The Visual C++ tools is odd because I think I should already have that, but I don't know how to check. I'll definitely do it and try again in a second however.
Same issues and text after restarting and opening with the visual studio and then just normally in the terminal.

Have you tried (re-)installing the Visual C++ Build Tools?
Note that it is not enough just to have Visual Studio. You also need to select specific components for C++ development. This page has some more details if you are using the Visual Studio installer rather than downloading the C++ build tools directly.
You don't need to run cargo clean here. This is only useful after building source code that you have downloaded yourself, not when downloading it from crates.io with cargo install.
I had downloaded the C++ build tools directly and then the Visual Studio, if I'm not mistaken by the links on the first page and the download instructions.
And my bad on the cargo clean thing, that's the only solution I'd seen for the cargo.toml file being missing. If there's nothing else that can help resolve the issues involving that and the
error: failed to compile `gifski v1.5.1`, intermediate artifacts can be found at `C:\Users\...\AppData\Local\Temp\cargo-installme3ok3`
error, how do I just uninstall everything and be sure everything involing rust and cargo is gone? I've just done rustup uninstall before each try (about five now, thinking it just needed to be redownloaded and would be right that time), but this is fairly frustrating.
According to this previous discussion, running your cargo install command via the “Native Tools Command Prompt” might fix the link.exe error. (I believe this is a shortcut that gets installed when you install the C++ build tools.)
After running rustup uninstall, I believe you can completely get rid of any remaining files by removing the .cargo folder in your home directory, and any folder starting with cargo under the AppData\Local\Temp directory.
I appreciate it. Wish I could also figure out what the fragments stuff means and the cargo.toml, but I don't see any solutions here for exactly what I'm looking for; guessing just deleting everything is the best option, once I find the App Data folder (the path they're suggesting literally isn't on my computer?). I appreciate the help, even if the problem wasn't solved. I know I'm probably frustrating to talk to involving this stuff since I'm an idiot, but I'm happy you were nice about everything.
I'm not sure what you mean by "fragments." What does this refer to?
It looks like the only problem is that the Rust compiler isn't able to find the linker for some reason. Using the Native Tools Command Prompt may fix this.
But if you just want to install gifski, downloading it from https://gif.ski/ should definitely be easier than installing and using Rust/Cargo.
Deleted the .cargo and .rustup files, just to update.
If there's anyway to do a clean install with everything intact, let me know, but just going from the .exe apparently isn't working on my machine for whatever or with my pea-brain (lol).

That's the issue, I do have a version of it from the link you've sent already, but when trying to run a specific task (ie. parsing a mp4 into a gif), if says to do "cargo install gifski --features video" or something along those lines without any other option. The base form just calls for you to literally rip every frame from an mp4 into pngs with ffmpeg and then convert the frames into a gif. I can do that, but that is incredibly tedious as you can imagine. That's the only reason I'm trying to get this Rust/cargo thing to work, honestly, just convenience with one app. I'm not used to the few CLI tools I use giving me this much of a hassle beyond pretty simple text entry.

I was able to find the folder in which the cargo-install folders resided, but I can't tell what's wrong with them or what the artifacts would be. Should I delete them all?
You can delete these. These are temporary files created during the failed builds. Normally they would be deleted automatically, but Cargo kept them around after the error in case they were needed for debugging.
Thanks again. Not sure what the "artifacts" in the folders are supposed to mean, but I deleted them all. If there is a proper way to download/run the rust .exe from the start, I'm all ears, but nothing has worked thus far; I appreciate the help and the cordiality of everything. The Native Command Prompt solution lead to… you guessed it… the same error.

I'm just convinced that I'm cursed at this point, seeing as literally nothing I've found online has helped.
I have to be totally honest with you, I have absolutely zero idea what that means. If you don't mind, could you briefly explain or link something? I'm a total novice to this kind of stuff, the most tech-whiz stuff I can do is use basic command line programs and make basic websites with knowledge from one coding class in college lol. I think me running into the same issue seemingly no one else seems to have is proof enough that I don't know what I'm doing.
Tried it, didn't work.

I was more thinking out loud; I don't know anything about gifski. I suggest trying the commands I posted and seeing if they are successful. The (hopefully) worst that can happen is they still don't work.
Explanation: Rust supports two toolchains for compiling on Windows: x86_64-pc-windows-msvc, which uses the Microsoft provided Visual C tools (e.g. link.exe), and x86_64-pc-windows-gnu which uses an alternative, open source, set of tools (also called "mingw"). I have heard of other people who, after having a hard time getting Rust to correctly locate link.exe (the same error you are getting) were able to use the alternative gnu toolchain to successful compile projects.

A few more comments on different boards seem to suggest that this is a lot more trouble than I was expecting. I appreciate the help here, especially from @mbrubeck who actually helped me learn a decent bit indirectly about Rust despite me really just coming for one app.
