cargo-udeps VS dmd

I'm releasing cargo-udeps 0.1.33 today. The release marks a big change in the evolution of cargo-udeps, as the default backend is changed from using save-analysis to depinfo. This change was needed because the compiler is removing support for save-analysis. I will remove support for the save-analysis backend entirely in a couple of weeks, when the 1.64 release is made, and I'll update cargo-udeps to the new cargo release.

rust-analyzer only provides a handful of diagnostics by itself, everything else is forwarded from cargo check (if checkOnSave is enabled). Neither tool currently emits a warning for unused dependencies, since it's pretty hard to do, but cargo-udeps can do it (though I'm not sure how reliable it is).

Maybe an extension to cargo-udeps?

cargo-udeps does a great job at letting us know which dependencies in our `Cargo.toml` are left unused. I am pretty impressed with it.

You can also turn off debuginfo completely. Personally, someone who does printf debugging, I mainly need it to debug segfaults, which are really rare in Rust. Sometimes the call stack of a panic is useful as well, but if I need debuginfo I can just re-enable it.

Here's the pipeline spitting out the same error as on my macbook did.

Not completely on topic (if you read TFA) but my favorite Git commit is by compiler badass and HN frequenter, where he checks in an entire C compiler to the D language repo:

A new generated code alone is 4000 lines long [1]. The actual code added is just 2000 lines, and some are used to pay debts, I mean, to make a proper code generator (which can be alternatively written in a simpler scripting langauge). In any case it is never comparable to the entier C parser proper.

D is completely opensource already (https://github.com/dlang/dmd). The "open" of OpenD is just ADR saying that OpenD will be more open to new language features than D has historically been.

The reference compiler, DMD, is open source: https://github.com/dlang/dmd

But they don't accept just any Pull Request or features the community submits, understandably. There's a process called DIP for language improvements: https://github.com/dlang/DIPs/blob/master/DIPs/README.md

However, by some accounts, it's really hard to get anything through.

Given D already has so many feature, I find that to be a good thing , to be honest, by not everyone agrees, of course.
