What does the core Rust team think of Crates.io? Is it supposed to be a proper use of the site to be posting full fledged GUI apps and Blogs in the crates repo? Or is just another Crates.io a third party package repo?
The crates.io website is meant to be the online interface to Rust's package registry.
That said, I'm just some random guy on the internet and not affiliated with the crates.io team.
The standard advice is that applications for Rust developers should live on crates.io, but if you’re providing something for non-Rust folks, you should also build native packages and pre-built binaries for them.
But nothing stops you from putting whatever you want up there, and we don’t enforce this at all; it’s a suggestion for the benefit of your users, not a rule.
