json-spanned-value VS rust

> The nonsense end result of that line of logic is that you return a single boolean that corresponds to failure/success, so I assume that's not what you mean.

I frequently find that is all that is necessary, and is exactly the correct solution, not "nonsense" whatsoever. Perhaps even that boolean is overkill: an unrecoverable bug should perhaps instead log and then terminate, producing no error condition for the caller of your library to worry about attempting to recover from whatsoever. Detailed error reporting can be done without obscenely distinct error types, and in fact detailed error reporting frequently benefits from a focus on the task itself instead of trying to structure data to leave the task of actually reporting the error to someone else, and kicking the can down the road.

E.g. for parsing focused errors like this I'd be more interested in pretty printing the source line in question, underlining the error, etc. - I wrote https://github.com/MaulingMonkey/json-spanned-value for helping ease the display of bad JSON data in a manner that integrates with your IDE for ease of fixing said data by jumping directly to the cause.

And then, admittedly, there are times when different errors should be recovered from differently. When the caller might wish to retry an operation after some errors, try a different operation after other, report file+line+range information for yet other errors, etc. - these have very concrete answers to "What do you expect the user of your library to do with this detailed information?" that are not difficult to answer at all.

> Contrast the two error messages:

Both are UTF8 strings without types adding anything obviously useful. A silly demo screenshot of errors that will open the offending document if closed, and navigate to the line/column of said error:

https://github.com/MaulingMonkey/json-spanned-value/blob/mas...

Which operates by immediately dumping the "errors" to terminal without any types involved whatsoever... nor even a boolean branch! Well, a real program might set a boolean so the CLI knows to exit(1) instead of using partially parsed data...

You are responding to one of the key developers of Rust early on[1], who's been working with the language for 14 years at that point.

[1] https://github.com/rust-lang/rust/graphs/contributors?from=2... and he's still #16 in commits overall today, despite almost no activity on the rust compiler since 2014.

If you haven't dipped your touch-typing fingers into Rust yet, you really owe it to yourself. Rust is a modern programming language with features that make it suitable not only for systems programming -- its original purpose, but just about any other environment, too; there are frameworks that let your build web services, web applications including user interfaces, software for embedded devices, machine learning solutions, and of course, command-line tools. Since a custom GitHub Action is essentially a command-line tool that interacts with the system through files and environment variables, Rust is perfectly suited for that as well.

Here's an example of someone citing a disagreement between CRT and shell32:

This in addition to the Rust CVE mentioned elsewhere in the thread which was rooted in this issue:

https://blog.rust-lang.org/2024/04/09/cve-2024-24576.html

Here are some quick programs to test contrasting approaches. I don't have examples of inputs where they parse differently on hand right now, but I know they exist. This was also a problem that was frequently discussed internally when I worked at MSFT.

Yeah, they didn't follow the instructions and got burned. I still think that multiple things went wrong simultaneously for that experience. I wonder if more prevalent uses of `#[doc(alias = "name")]` being leveraged by https://github.com/rust-lang/rust/pull/120730 (which now that I check only accounts for methods and not functions, I should get on that!) so that when changing APIs around people at least get a slightly better experience.

Almost fixed the compiler: https://github.com/rust-lang/rust/pull/123325

Rust: A secure, efficient, and modern programming language (omitting ten thousand words). You can simply follow the installation instructions provided on the official website.

Recently did something similar in Rust but for generating SVGs. We've adopted it for snapshot testing of cargo and rustc's output. Don't have a good PR handy for showing Github's rendering of changes in the SVG (text, side-by-side, swiping) but https://github.com/rust-lang/rust/pull/121877/files has newly added SVGs.

To see what is supported, see the screenshot in the docs: https://docs.rs/anstyle-svg/latest/anstyle_svg/

We strongly believe in Rust as a powerful language for building production-grade software, especially for systems like ours that run alongside Kubernetes.
