docs.rs can't build

[roberth]

docs.rs fails in our build.rs.

Solutions and workarounds:

A: Make our build.rs succeed

If they only need build.rs and not a real compilation, this could work.
-sys crates will be empty.

You can customize docs.rs builds by defining [package.metadata.docs.rs] table in your crates' Cargo.toml.

B: Get docs.rs to install Nix in their docs building sandbox

NOT the Nix libraries, but the tool, enabling all Rust packages to retrieve their deps through Nix, giving them a lot more flexibility.
Prior art for this: replit, firebase

C: Ubuntu package

Easy, but lags behind. Docs.rs requires Ubuntu 24.04 as of writing.
nix-bin was added in 25.10, at Nix version 2.26, which has C API, but lacks more recent additions

D: Get docs.rs to accept locally built docs

Requires a bit more setup on our end.
They probably shouldn't trust third party HTML/CSS.
