hippo VS lang-team

You may laugh, but a few years ago all those guys who sold us (some of? us - me anyway) on Kubernetes evidently got bored with it, and now they're all building a Hippo Factory[1]. And it's actually really good. This is the current timeline!

WebAssembly (Wasm) is something that the Cloud Native Advocacy team has been exploring. It has been around for a few years and has mostly been used within browser-based applications. There are many blog posts on what makes WebAssembly an ideal target for running applications (e.g., smaller footprint with .wasm files compared to containers, code isolation, and sandboxing). My colleague Steven Murawski wrote a blog series on getting started with hosting Wasm apps on an emerging PaaS platform called Hippo which is developed by folks at Fermyon. In Part 1 of the series, he introduces topics and define some of the acronyms like "Wagi" and "WASI". He also introduced a runtime called Wasmtime which implements the WebAssembly System Interface (WASI) standard. This article will walk you through how Steven and I went about getting a .NET console app running as a Wasm app on the Wasmtime runtime in a Dev Container. The .NET console app produced in this article has also been contributed as a csharp template in the yo-wasm repo which is also maintained by Fermyon; so you can quickly test it out for yourself later.

The Rust team did a deep dive on the bug in 2020, which has some more details that might be helpful to understanding what's going on: https://github.com/rust-lang/lang-team/blob/master/design-me....

I haven't been following this closely, so I looked it up and it looks like that's not going to happen for the foreseeable future unfortunately:

https://github.com/rust-lang/lang-team/issues/122

Kind of a shame, but wrapper types work well enough that I understand. It does look like if there was someone with enough resources to make it happen that they'd be receptive to it.

Did you read the link the original comment posted? I think that explains the idea rather well https://github.com/rust-lang/lang-team/issues/122

A quick search pulled up this as a likely candidate for most recent discussion of it but it goes back at least to 2016 with this RFC.

There have been at least one proposal and RFC in the past that seem to be deferred or closed due to bandwidth issues.

That's what Rust does, and it's considered a problem (that the devs are regrettably unable to reasonably solve) rather than a good thing.

Lang had some conversations about this: https://github.com/rust-lang/lang-team/issues/139

The design of Rust panics unconditionally aborts the program if you panic while unwinding, and some people even want to abort if you panic in Drop.

> Better interoperability

AFAIK, the examples you give all target a basic C ABI [0] or can be made to target the same ABI. In Rust, it means targeting wasm32-unknown-emscripten

The Rust team is also working on a "WASM ABI"[1] which would be useful in taking advantage of stuff like multi-value returns, and other compilers could just choose to target that. More likely, the C ABI on WASM will be updated to account for missing features, and that'll be the standard for interoperability in the WASM ecosystem.
