Actually, all of it applies to rust. The only stable ABI in Rust is C-ABI and IMO at that point it stops being rust. Even dynamically loading rustlib in rust application is unsafe and only expected to work when both compiled with the same version. In plugins context, it's the same as what Caddy making you do.
However, Rust Evangelical Strike Force successfully infiltrated WASM committee and when WASM Components stabilize, it can be used for plugins in some cases (see Zed and zellij). (Go can use them as well, rust is just the first (only?) to support preview-2 components model.
Yeah, I don't really do dynamic loading in my corner of Rust. And I can always target some MSRV, cargo package versions, and be happy with it. Definitely beats the dependency hell I've had to deal with elsewhere
Don't get me wrong, I love rust and use it almost every day. Doing `cargo run` in a project it handles everything is good. This gets lost once you start working in a plugin context. Because now you're not dealing in your neatly organized workplace, you're working across multiple workplaces from different people.
IIRC it's more than just MSRV or even matching version exactly. It also requires flags that were used to compile rustc match (there is an escape hatch tho).
