The main issue I have with rust is the lack of a rust abi for shared libraries, which makes big dependencies shitty to work with. Another is a lot of the big, nearly ubiquitous libraries don’t have great documentation, what’s getting put up on crates.io is insufficient to quickly get an understanding of the library. It’d also be nice if the error messages coming out of rust analyzer were as verbose as what the compiler will give you. Other than that it’s a really interesting language with a lot of great ideas. The iterator paradigm is really convenient, and the way enums work leads to really expressive code.
As someone that have worked in software for 30 years, and deplying complicated software, shared libraries is a misstake. You think you get the benefit of size and easy security upgrades, but due to deployment hell you end up using docker and now your deployment actually added a whole OS in size and you need to do security upgrades for this OS instead of just your application.
I use rust for some software now, and I build it with musl, and is struck by how small things get in relation to the regular deployment, and it feels like magic that I no longer get glibc incompatibility issues.
Technically this is conflating two things: bundling dependencies and static/dynamic linking. But since you have to bundle your dependencies to use static linking, and there’s little point dynamic linking if you bundle your dependencies… most of the time they are synonymous.
Exceptions are things like plugins, but that’s pretty rare.
Documentation is generally considered one of the stronger points of rust libraries. Crates.io is not a documentation site you want https://docs.rs/ for that though it is generally linked to on crates.io. A lot of bigger crates also have their own online books for more in depth stuff. It is not that common to find a larger crate with bad documentation.

Maybe tackle that deployment hell instead of band-aiding it with docker?
He is. By using statically linked binaries.

Why not just use the C ABI?
And what libraries are you referring to? Almost all the ones I’ve used have fantastic docs.
In my understanding, you can’t interface with the C abi without using an unsafe block.
I think there are some crates that wrap the unsafe code for you, e.g. https://github.com/rodrimati1992/abi_stable_crates/ (I haven’t ever tried it).
