cargo-deny VS cross

Tip: You can check the licenses of all your dependencies (recursively) using cargo-deny: https://github.com/EmbarkStudios/cargo-deny

cargo-deny

cargo-deny can help block specified versions of a crate and even has some advisory features that can probably used to block crate with reported vulnerabilities

cargo deny for fetching crates only from trusted sources, blacklisting crates, etc.

Use cargo audit or cargo deny to check the crates in your Cargo.lock to ensure they don't contain any vulnerabilities.

> Explain the crate scanner thing?

I assume a reference to tools that help manage potential issues around dependencies, e.g.:

* https://github.com/rustsec/rustsec/tree/main/cargo-audit

* https://github.com/EmbarkStudios/cargo-deny

"[cargo-audit] Audit Cargo.lock files for crates with security vulnerabilities reported to the RustSec Advisory Database."

"cargo-deny is a cargo plugin that lets you lint your project's dependency graph to ensure all your dependencies conform to your expectations and requirements." e.g. license, security advisories, source.

cargo-deny does license and security advisory checking, and cargo-geiger does unsafe checking.

OpenSSL has been banned in our project for a variety of reasons via cargo-deny for around a year and half, it was actually one of the reasons we created it in the first place.

To compile a program with musl on a glibc system you can use cross-rs!

I cross compile to Mac, bsd, windows, etc cross ... Works great for me with either docker or podman.

If docker is available for you, https://github.com/cross-rs/cross is another and reliable way to solve this kind of problem. I do use it regularly.

We are using https://github.com/cross-rs/cross.

There is some built-in support in rustc for cross-compiling, but getting the build to actually work can be tricky due to the need for an appropriate linker. Instead, we’re going to use the Cross crate, which used to be maintained by the Rust Embedded Working Group Tools group.

I have used cross before to cross compile from Linux to other Linux. It has a section on it's wiki about this. Maybe that could be of help.

You can use cross to build your application and copy the artifacts into an alpine armv7 container. It would also build faster due to using cross compilation rather than QEMU.

Looks like cross is the easiest way to get something cross-compiled but its Mac support is blocked behind building your own build image. Even that repo says that it might be broken.

Bonus: if you’re working with Rust and doing a lot of cross platform stuff, check out cross. It runs QEMU in docker so you can run tests on a bunch of different emulated targets easily- literally a one line setup, it’s kind of magical.

It's also not as naturally cross-compilable as Go, though that's partly a side-effect of not accepting being a semi-closed ecosystem to achieve that and cross exists as a stop-gap while things like cargo-zigbuild explore less drastic options.
