std-training VS rust

It's well established that interrupts are a tough concept to grasp for the embedded beginner. Add to that when doing it in Rust the complexity of dealing with mutable static variables. This is because working with shared variables and interrupts is inherently unsafe if proper measures are not taken. When looking at how to do interrupts using the esp-idf-hal I first resorted to the Embedded Rust on Espressif book. Interrupts are covered under the Advanced Workshop in section 4.3, and to be honest, I was taken aback a little at what could be an additional level of complexity for a beginner. Without too much detail, this is because the book resorts to using lower-level implementations. For those interested, by that, I mean FFI interfaces to FreeRTOS which I will be creating a separate post about later.

Relative to the esp-idf-hal , as far as material goes, there exists training material that is open sourced by Ferrous systems. The training material takes a bit of a different approach where it starts with high-level IoT exercises followed by low-level control. Additionally, the training is based on the awesome Rust ESP board hardware.

Yes! The training developed with Ferrous Systems (https://esp-rs.github.io/std-training/) contains several examples, and you can find many community projects in https://github.com/esp-rs/awesome-esp-rust#projects

Good places to get started with std Rust on ESP include the Rust on ESP book, Embedded Rust on Espressif by Ferrous Systems. There's also the Awesome ESP Rust GitHub repository that contains a lot of useful material and project examples.

Embedded Rust on Espressif (Ferrous Systems training)

I must admit I've never used it for anything but tutorials yet (kids resulted in a lot of personal projects shelved), but Rust has an amazing and rapidly developing embedded ecosystem. A good starting point to get an impression of it might be training materials from Ferrous Systems 1, 2 (feel free to pay for the training itself if you feel like it's worth it for you of course). There is an embedded working group for Rust, Knurling project to improve tooling and even an attempt of Rust standard certified for safety-critical application.

Rust

It seems to be more fussy about compiler optimizations, though: https://github.com/rust-lang/rust/issues/125543

apimock-rs is one of my projects on API mock Server generating HTTP/JSON responses to help to develop microservices and APIs, written in Rust.

Rust, the language itself depends on 220 packages: https://github.com/rust-lang/rust/blob/e8753914580fb42554a79...

If you trust nobody, it is hard to use anything.

But about your second note, (environment, mismatched dependencies), I would argue that Rust provides the best tooling to solve or identify issues on that area.

rustc source code

First look is into The Unstable Book. Well, it does not look informative but gives us some background from the rust-lang Github project-const-generics. It says:

Rust has been around for several years and works well as a system and general programming language. There are many fine introductions to the language, a good place to start is here: https://www.rust-lang.org/

‍For the rest of this post I’ll list off some more tactical examples of things that you can do towards this goal. Savvy readers will note that these are not novel ideas of my own, and in fact a lot of the things on this list are popular core features in modern languages such as Kotlin, Rust, and Clojure. Kotlin, in particular, has done an amazing job of emphasizing these best practices while still being an extremely practical and approachable language.

You are responding to one of the key developers of Rust early on[1], who's been working with the language for 14 years at that point.

[1] https://github.com/rust-lang/rust/graphs/contributors?from=2... and he's still #16 in commits overall today, despite almost no activity on the rust compiler since 2014.

If you haven't dipped your touch-typing fingers into Rust yet, you really owe it to yourself. Rust is a modern programming language with features that make it suitable not only for systems programming -- its original purpose, but just about any other environment, too; there are frameworks that let your build web services, web applications including user interfaces, software for embedded devices, machine learning solutions, and of course, command-line tools. Since a custom GitHub Action is essentially a command-line tool that interacts with the system through files and environment variables, Rust is perfectly suited for that as well.
