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.

ESP32 example project
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 :(
-
Are there any Rust forks out there?
Sure. Espressif maintains a fork which adds support for their microcontrollers.
-
Would it be possible to compile openssl-sys for esp32
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.
-
Are there situations where it's better to use C++?
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.
- Rust-Xtensa: Rust for Xtensa Processors. Built in Targets for the ESP32/ESP8266
-
Multi-use kernel written in Rust
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.
- Could IOTA transaction be started solely from the IoT capable device (like esp32)?

Rust on Esp32
There is a template for how to use Rust from an idf.py cmake project where you can incrementally add Rust to your project by calling to from C. Instructions for it are at https://github.com/esp-rs/esp-idf-template/blob/master/README-cmake.md

ESP32 example project
Sorry for the poor way of supporting you, I am currently at the embedded world and I can't try much to reproduce your issue. I just merged: https://github.com/esp-rs/esp-idf-template/pull/84. Which can be what you were facing, can you use the latest template and see if the issue still persists? Let me know how it goes
