cargo-zigbuild VS aws-sdk-rust

https://github.com/rust-cross/cargo-zigbuild

I’m curious what the blockers are for rustc to cross-compile like zig does natively.

Perhaps you can try cargo-zigbuild, it uses zig-cc for cross-compilation instead of creating a container, so it should be much more lightweight on MacOS, without all the cost of virtualization and file sharing.

I have tried, however I haven't been able to get it to work reliably (e.g. building on windows + linux on WSL works, Mac is a lot more involved; tried building for windows + linux on Mac and I couldn't get it to work at all); I've had some luck using zigbuild but that too doesn't seem to work for Mac.

Zig also takes this approach, and even exposes its C compiler (which if I recall correctly is basically Clang plus diverse sysroots and other customisation out of the box) as a separate `zig cc`.

I do a lot of work in Rust, and cross-compilation can be a pain when you have a lot of C dependencies. Fortunately https://github.com/messense/cargo-zigbuild exists. It sounds crazy, but using Zig's inbuilt C compiler to help build my Rust projects has been the smoothest option I've found.

I can't help but wonder if it would be worth it for Rust to follow D and Zig by shipping its own inbuilt C compiler, even if they still want to also support external C toolchains. It should be roughly the same effort as it was for Zig, given that they both use LLVM.

Wait until you start using cargo zig-build. Suddenly it becomes way better than Go's cross compiler because you can seamlessly cross-compile rust AND C (thanks to Zig compiler of course). https://github.com/messense/cargo-zigbuild

The AWS SDK for Rust contains one crate for each AWS service - you can check them out here.

> What kind of plans for support of Rust's evolving async ecosystem?

We were hoping async-function-in-trait would land before GA, however, we have a plan to add support in a backwards compatible way when it's released.

> Any particular reason why the public roadmap does not show the columns similar to "Researching", "We're Working On It" like the other similar public AWS Roadmaps?

Our roadmap has unfortunately been in a state of disrepair for some time. We're hoping to get it cleaned up and accurate post GA.

> Would be nice to have fully working examples on Github, for most common scenarios across most AWS services. This is something that historically AWS SDKs have been inconsistent on. Just a request not really a question :-)

There are lots of examples here [1], some simple, some quite complex. If there's something you have in mind, please file an issue! Having great examples is one of our priorities.

There’s a pretty nice example of this in the aws rust sdk here.

The official AWS Rust SDK still seems to be a work in progress(developer preview) with a warning to not use it in production.

i'm using https://github.com/awslabs/aws-sdk-rust heavily and was wondering if there was a more specific community (subreddit, Discord server, etc) of Rust x AWS developers?

Only relevant search result was this github issue, which didn't really solve the problem.

I went on rusoto just because aws-sdk-rust says at the beginning of the readme:

Official libraries for major cloud vendors will definitely boost Rust's adoption. aws-sdk-rust is still in 'developer preview', but it's getting there.
