checkedc
Checked C is an extension to C that lets programmers write C code with bounds checking and improved type-safety. The goal is to let people easily make their existing C code type-safe and eliminate entire classes of errors.

Rust Dependencies Scare Me
You want a special purpose language.
In your particular example of image loading, you want WUFFS. https://github.com/google/wuffs
In WUFFS most programs are impossible. Their "Hello, world" doesn't print hello world because it literally can't do that. It doesn't even have a string type, and it has no idea how to do I/O so that's both elements of the task ruled out. It can however, Wrangle Untrusted File Formats Safely which is its sole purpose.
I believe there should be more special purpose languages like this, as opposed to the General Purpose languages most of us learn. If your work needs six, sixteen or sixty WUFFS libraries to load different image formats, that's all fine because categorically they don't do anything outside their box. Yet, they're extremely fast because since they can't do anything bad by definition they don't need those routine "Better not do anything bad" checks you'd write in a language like C or the compiler would add in a language like Rust, and because they vectorize very nicely.

Fast-PNG: PNG image decoder and encoder
wuffs has standalone C header for png decoding that is safe and very fast: https://github.com/google/wuffs/blob/main/doc/std/image-deco...
There's also libspng, supports encoding & decoding, but it does not seem to be very maintained anymore, and it has extra dependency on zlib/miniz: https://github.com/randy408/libspng

Why do I find Rust inadequate for text compression codecs?
This kind of hyper-specific need (codecs) is probably better served by a specialist language, like Whuffs (https://github.com/google/wuffs). You don't need, or want, the level of expressiveness that comes with something like Rust, but on the other hand, it's a compact enough problem set that you're willing to spend extra development work to eke out every bit of speed.

RealtimeSanitizer for Rust
I only have grug brain, but one could call WASM modules each with its own tiny memory pre-allocated. There is also WUFFS the language which is explicitly limited in several ways. I also feel like some things could be done in Ada or one of the more strict functional languages.

CrowdStrike debacle provides road map of American vulnerabilities to adversaries
Again, there are safe ways of doing this. For example, Wuffs exists: https://github.com/google/wuffs
At the very least, big money security software companies should be parsing untrusted content with some kind of rigorouly safe approach, not just squirting it through a big pile of C/C++.
And don't get me started on the whole concept of undefined behavior in those languages. To quote I. I. Rabi, "Who ordered that?"

> Rust was literally invented to solve the security and concurrency issues inherent in using C/C++ for a browser engine.
Are most browser vulnerabilities not still found in engines like V8? Rust can help with something like last year's buffer overflow in libwebp (although that's overkill when a project like https://github.com/google/wuffs exists), but I'm unclear on how it gets you a better JIT.
