misra-rust VS book

MISRA and Ferrocene are not really related.

MISRA is, as you say, a set of rules for writing C code, that restrict what you can do.

Ferrocene is a qualified compiler. You write any normal Rust code you want: it's still the upstream Rust compiler. There are no restrictions.

Incidentally, someone has compared what MISRA does to what Rust does: https://github.com/PolySync/misra-rust/blob/master/MISRA-Rul...

Given that they can't repeat the MISRA stuff there, it's a bit disjoined, but it sure is interesting!

A fun github repo: "what would MISRA look like applied to Rust" https://github.com/PolySync/misra-rust/blob/master/MISRA-Rul...

(They're comparing with the C version, not the C++ version...)

> There are huge swathes of MISRA which forbid things which not only aren't possible in Rust or SPARK

I can't vouch for its accuracy, but https://github.com/PolySync/misra-rust

When it comes to MISRA C, it is interesting to note how many (a majority) of its rules do not apply or have native enforcement[1].

You might have also seen the AUTOSTAR Rust in Automotive Working Group announcement recently[2].

[2]: for some reason the announcement was removed from the "News and events" site, https://webcache.googleusercontent.com/search?q=cache%3Ahttp... but it is still available as a PDF https://www.autosar.org/fileadmin/user_upload/20220308_RustW...

There's actually already a comparison: https://github.com/PolySync/misra-rust/blob/master/MISRA-Rules.md

Rust makes quite a few things more rigorous (e.g. pairing allocations with deallocations and reference validity). It basically fulfills the job of a static analyzer baked into the language.

It's also a vastly more analyzable language (in that its syntax is reasonably unambiguous and there's no dynamic runtime in play) and it can be integrated well.

Toolchain quality (error reporting, built in testing, awareness of primitives like "libraries", etc.) is also a huge strong point.

We're reasonably confident that we can use safe Rust as is, with strong guidance on how to do unsafe Rust.

For a tangible investigation of that space, PolySync has a project that has a look at MISRA rules from a Rust perspective. https://github.com/PolySync/misra-rust/blob/master/MISRA-Rul...

Ada is a good example here: the language has not evolved something like MISRA-C (it has evolved SPARK for formal verification, but I see that differently).

My first port of call was to google learn rust which lead me to "the book". The book is a first steps guide written by the rust community for newbies (or Rustlings as they're called) to gain a 'solid grasp of the language'.

Before Prodzilla, I’d read 'The Book' a couple of times, and had made my way through Rustlings, but hadn’t yet built a serious project in Rust.

To answer your last question;

Start with the Rust book.

https://doc.rust-lang.org/book/

Then do Rustlings until the syntax becomes muscle memory.

Then join the Discord and start doing little projects.

You won’t get up to the proficiency of other languages as quickly in Rust. It takes longer. For me it’s taking a lot longer, but I enjoy it.

Before diving into these repositories, familiarize yourself with Rust and its development ecosystem. The official Rust book is an excellent resource for developers at all levels. Each repository has documentation on how to contribute, covering code style, issue tracking, and pull requests.

This is my third Rust book after the official book and Rust in Action. The other two books are great, but they were too theoretical for me. I'm a slow learner and had much trouble grokking Rust's features and idiosyncrasies. When I was done with these books, I was lost and unsure of what I could do.

It's the same reason everything digital and downloadable isn't free: there's a cost to create it and there's a value to it.

For a language developer to charge for a book about that language, I think that's a completely valid way to make some money off of their work.

Even the Rust book, "The Rust Programming Language" is available freely online [0], but also as a print and ebook for sale via NoStarchPress [1].

You know you can just read it online right now in 2 different variants It does contain some systems programming.

I am looking at The Book (https://doc.rust-lang.org/book/), but hoped there was an amazing person on youtube.

Yeah, I'll build something, finally trying webassembly.
