reference VS rust

Is perfectly valid Rust code. And there's reborrow, too.

I truly appreciate how much effort u/ehuss puts into maintaining The Rust Reference, considering that documenting stuff is not usually a fun task people want to do. Not to mention that ehuss is also the Cargo team lead, responsible for developing one of the most loved tools in Rust. ehuss's insightful knowledge always ensures that Cargo works without unexpected surprises.

Here is (somewhat long) discussion on the topic with other examples: https://github.com/rust-lang/reference/issues/788

The PR for updating the documentation is here, still under discussion: https://github.com/rust-lang/reference/pull/1055

thank you this is definitely interesting and i need to read more. For anyone else, this is the thing I found about this issue when I looked it up. It's a github issue about how little documentation there is on the subject and that there should be more. Even the initial post has a lot of interesting details and links. Thanks for bringing it up although sorry it seems your comment went a bit over the heads of some redditors.

⭐ The Rust Reference - repo

For the rust reference, there is an open pull request https://github.com/rust-lang/reference/pull/1265/

&mut * is reborrowing which is allowed

I've opened a PR to add this more prominently to the Conditional Compilation entry in the Rust reference.

The esp-template issue might be this one: https://github.com/esp-rs/rust/issues/158. Try with --release or updating to 1.68.0 with espup update. I'll take a look at the log as soon as I can, atm Im on the phone and is not that easy to scroll through :(

Sure. Espressif maintains a fork which adds support for their microcontrollers.

I am trying to make a vaccine passport validation for my country using the ESP32 for my micro controller. I have gotten the std rust library to compile using (esp-rs)[https://github.com/esp-rs/rust], but the actual validation library that I use needs openssl which refuses to compile.

Xtensa. They've got a fork of LLVM that supports it that they're working toward getting upstreamed. The community has a fork of rustc that uses it (and a quickstart crate) while we wait for it to get upstreamed.

It only works if you have an Xtensa compiler which takes hours to compile, here: Rust Xtensa (if you don't have it). The network driver is just a function that sets the name of the driver so the Esp32 does something other that blinking.
