What's in crate files?

I’ve run a quick analysis on directory listings of all crate files published on crates.io (to show a pie chart with crate contents of non-pure-Rust crates). Here’s top 100 of most common filename extensions:

It’s interesting that crates.io contains more html files than rust

Thant’s probably Cargo.toml.orig, which are created by Cargo:

During publishing, Cargo rewrites your Cargo.toml (to replace workspace path deps with real deps at least, and for something else as well I think), but it preserves original toml with .orig extension just in case.

Ah, indeed!

Well that’s a lot, but I suppose it entails the generated documentation for the crates?
