cargo-msrv VS rust

What this tool say? https://github.com/foresterre/cargo-msrv

I'm working on cargo-marv.

Before getting overcome by despair, have a look at cargo-msrv -- this little gem of a tool figures it all out for you!

I'll be adding a 'minimal' output format to cargo-msrv for use in scripts. I'll also be updating the book, and inch closer towards releasing v0.16.

First commit 2 months ago, started with edition 2021. https://hg.sr.ht/~cyplo/legdur/browse/Cargo.toml?rev=ca11815...

Have you tried compiling something less than bleeding edge, with a year old compiler, or are you picking projects specifically to "showcase" the supposed failings of the Rust compiler?

Many libraries in the ecosystem have a MSRV (minimum support rust version) guarantee, with compile-time shims to enable newer features if a more recent version is detected.

You can pin your dependencies to those versions (and if they don't have an explicit MSRV, just pin it to a version by date or by running https://github.com/foresterre/cargo-msrv on the project to find the effective MSRV).

You can cargo install specific versions of a binary crate, and if they move to the 2021 edition, or use a recently stabilized standard library function or w/e, you can simply choose to install a specific version, that would work with your distro's rustc/cargo.

I'm not even talking about the completely valid, but last resort strategy of many non-bleeding edge distro package maintainers, of simply creating a .patch file and applying it. In legdur's case, --- edition = "2021" +++ edition = "2018" on Cargo.toml would probably do the trick. For libraries/binaries you control, you can use https://doc.rust-lang.org/cargo/reference/overriding-depende... and https://github.com/itmettkeDE/cargo-patch.

Giving up after the first minor roadblock and crying bloody murder is intellectually lazy.

Looks helpful though it doesn't seem to address when you don't have a Cargo.lock. I've created an issue for this.

I'll be switching over the CLI of cargo-msrv, from Clap's builder methods to the attribute macro. I hope this will simplify the configuration, as my Config and ConfigBuilder structs (which were build from Clap's ArgMatches) was growing fast, and becoming slightly unorganized. With the attribute macro, the config will be constructed directly by code generated by the macro. The mostly saves one intermediate step, and a lot of boilerplate.

Some combination of cargo-outdated and cargo-msrv could probably do this in a slightly more manual fashion.

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.

Here's an example of someone citing a disagreement between CRT and shell32:

This in addition to the Rust CVE mentioned elsewhere in the thread which was rooted in this issue:

https://blog.rust-lang.org/2024/04/09/cve-2024-24576.html

Here are some quick programs to test contrasting approaches. I don't have examples of inputs where they parse differently on hand right now, but I know they exist. This was also a problem that was frequently discussed internally when I worked at MSFT.

> instead of choosing a certain numbered version of the random library (if I remember correctly) I let cargo download the latest version which had a completely different API.

Yeah, they didn't follow the instructions and got burned. I still think that multiple things went wrong simultaneously for that experience. I wonder if more prevalent uses of `#[doc(alias = "name")]` being leveraged by https://github.com/rust-lang/rust/pull/120730 (which now that I check only accounts for methods and not functions, I should get on that!) so that when changing APIs around people at least get a slightly better experience.

Almost fixed the compiler: https://github.com/rust-lang/rust/pull/123325

Rust: A secure, efficient, and modern programming language (omitting ten thousand words). You can simply follow the installation instructions provided on the official website.

Recently did something similar in Rust but for generating SVGs. We've adopted it for snapshot testing of cargo and rustc's output. Don't have a good PR handy for showing Github's rendering of changes in the SVG (text, side-by-side, swiping) but https://github.com/rust-lang/rust/pull/121877/files has newly added SVGs.

To see what is supported, see the screenshot in the docs: https://docs.rs/anstyle-svg/latest/anstyle_svg/

We strongly believe in Rust as a powerful language for building production-grade software, especially for systems like ours that run alongside Kubernetes.
