The same reason Bazel builds avoid using Cargo when building Rust software, so I'll describe why Bazel would do this:

- Bazel wants to cache remote resources, like each respective crate's source files.

- Bazel then wants to build each crate in a sandbox, and cache the build artifacts

This is an established practice, and Nix wants to drive the build for the same reasons.

See:

To answer your question, I don't know if Soong or Bazel can reuse the files produced by an incremental Rust compilation. I tried searching the rules_rust repository and found some discussions, but nothing that clearly told me "Yes, this is supported".

Bazel doesn't allow targeting a lot of platforms (especially embedded) from Rust, even when the Rust ecosystem supports these targets. Something is off with its design if new work needs to be done for every platform that's already available behind an interface that's as consistent as what rustc gives.

What is supported needs to be inferred from this file, as far as I can tell: https://github.com/bazelbuild/rules_rust/blob/main/rust/plat...

You might be overjoyed to learn that you can use a build tool that forces you to manually write out the dependencies between each file.

I am using rules_rust and have the VS Code Bazel plugin installed, but I am still not getting autocomplete.

Other than that, the performance of both for builds should be determined exactly by the organization of code into separate crates and the rustc invocations. Bazel generally encourages smaller crates, but that's very subtle. There is at least 1 case I can think of where rustc is overfit to cargo, in a way that is not easily replicable by bazel, which is the metadata/rlib pipelining https://github.com/bazelbuild/rules_rust/issues/228

Rust integrates pretty seamlessly into Bazel projects via rules_rust (https://github.com/bazelbuild/rules_rust). The existing rules even allow for c calling rust and rust calling c. Example: https://github.com/bazelbuild/rules_rust/blob/main/examples/...

With any compiled language you can use the compiler and vendor your dependencies instead of using the language's conventional package manager. For example, nothing prevents skipping Cargo and building Rust directly with rustc the way Bazel does.

FWIW regarding the package manager, based on the rest of the text my guess is that whoever wrote this intended to say that "Zig will ship with a package manager".

I created https://github.com/ziglang/www.ziglang.org/pull/228 let's see if it gets accepted :)

It looks like the HTML for the website is here, which gets built from the source documentation here.

Sorry to pull the rug out from under ya'll like this but that article was a couple years old, so I gave it a once-over pass to update it. Mainly the "No hidden allocations" section is rewritten. You can see the full commit diff here: https://github.com/ziglang/www.ziglang.org/commit/bede1e57b6...
