is https://docs.rs DOWN?
To get docs for your project, working offline:
cargo doc --open
or to get docs for just one specific crate/package:
cargo doc --open --no-deps -p package
Is there a solution to generate docs for a crate that is not added to dependencies of Cargo.toml?
You'd probably have to add it temporarily to
Cargo.toml, or clone its repo and run
cargo doc there.
