- Add API documentation links to all Cargo.toml files
- Add API documentation links to all crate READMEs
- Add API Reference link to main README
- Add Hercules CI effect to push docs to gh-pages on main branch
NCI's doc-merge doesn't support rustdoc's sharded search index format
(Rust 1.78+), so we build all workspace crates together in a single
cargo doc invocation. This enables cross-crate linking and produces
a custom index page with rustdoc-matching theme support.
Moves treefmt-nix input and configuration from the main flake to the
dev partition, since it's a development-only dependency. Also switches
pre-commit hooks from individual formatter hooks to the unified treefmt
hook for better consistency.
In the previous update commit, the Nix `cc.version` didn't match the
in-output directory name anymore, causing a build failure.
By asking GCC properly, we are robust against such discrepancies.
The script isn't great, relying on GCC "log" output specifics, but it
seems that the GCC output has been like this for a while, and the
lines before and after seem to be intentional about their purpose...
