Our great sponsors
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Isolates, MicroVMs, and WebAssembly (In 2022)
On Micro-VM's specifically, shout out to Wyrcan[1], which similar-ish to Fly.io is taking a container image & booting into itv an advanced & secure bootloader for a container image.

Totally_safe_transmute, Line-by-Line
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....

Using enums to represent state in Rust
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.
- Should Error enums be `non_exhaustive`?

What features would you like to see in rust?
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
-
Pattern matching tuple variant of enum without deconstructing tuple
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.

State Machines III: Type States
There have been at least one proposal and RFC in the past that seem to be deferred or closed due to bandwidth issues.
-
The type system is a programmer's best friend
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.

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

LKML: Linus Torvalds: Re: [PATCH v9 12/27] rust: add `kernel` crate
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.

Isolates, MicroVMs, and WebAssembly (In 2022)
> 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.
