unsafe-libyaml VS doom

The same is not true for CLIs, especially CLIs that don't use async networking. The space has matured incredibly well and almost everything you touch is bulletproof. Clap 4 with derive macros is one of the best libraries of any kind in any language I've ever used. Rayon makes totally safe parallel processing look like a rigged demo that can't possibly be real. Reading and writing JSON and TOML is silky smooth and fast, YAML is held together with sticky tape but it works too. There are incredible libraries like crossterm and tui to make terminal interfaces better and easier and more portable than anything in Go. People say Go is good for CLIs, but I think they must be comparing to Java or something, because Rust runs circles around Go for CLIs, and in ways that end users notice too.

I used it with great success for transpiring libyaml from C to Rust. I even set up Miri to run the upstream library's entire transpiled test suite, and the fact it passes is validation of absence of UB in the original C code.

The transpiled library now serves as the YAML backend for the widely used serde_yaml crate. Having serde_yaml be pure-Rust code instead of linking C is advantageous for painless cross-compilation as well as making downstream projects runnable in Miri.

Looks like the ~90-100% autofree and then reference counting, is a good memory management, and is very practical too, as proved by translating DOOM from C to V and building it in 0.7 seconds

Excuse me? Work on the V operating system has begun, the C->V transpiler can kind of handle a single Doom source file at this point and the Volt app, for which V was created in the first place, is going to get open-sourced any day now.

I believe that you're talking about doom repository. If that's the case, how'd I believe that it was indeed done using C2V when it's non-existent (checked the repo, it's still empty). A simple AST parsing python script with some heuristics can achieve one time conversion, that doesn't mean that it would work for all C programs.
