A cargo plugin for serving rust and crate doc locally.

$ cargo docs --help
Usage: cargo docs [OPTIONS] [EXTRA_ARGS]...

Arguments:
  [EXTRA_ARGS]...  Passthrough extra args to `cargo doc`

Options:
      --host <HOST>                    Set host [env: HOST=] [default: 127.0.0.1]
  -p, --port <PORT>                    Set port [env: PORT=] [default: 8080]
  -r, --random-port                    Use random port [env: CARGO_DOCS_RANDOM_PORT=true]
  -s, --search <ITEM>                  Search for item
  -d, --dir <DIR>                      Serve directory content [env: DIR=]
  -c, --manifest-path <MANIFEST_PATH>  Crate manifest path [default: Cargo.toml]
  -w, --watch                          Re-generate doc on change [env: CARGO_DOCS_WATCH=]
  -o, --open                           Open in browser [env: CARGO_DOCS_OPEN=true]
  -b, --book                           Serve rust book and std doc instead
  -h, --help                           Print help information
  -V, --version                        Print version information

By default, it will call cargo doc to build crate doc and start a local server.

Add --book option to see rust doc instead.

Install

$ cargo install cargo-docs

Examples

Serve crate doc on random port and open in browser

$ cargo docs -ro
[INFO] Serving crate doc on http://127.0.0.1:45669
[INFO] Opening http://127.0.0.1:45669

Same as above plus automatically rebuild and reload on file changes.

$ cargo docs -row
[INFO] Listening for changes...
[INFO] Serving crate doc on http://127.0.0.1:45669
[INFO] Opening http://127.0.0.1:45669

Serve rust docs instead (roughly the same as cargo-book)

$ cargo docs -bro
[INFO] Serving rust doc on http://127.0.0.1:46661
[INFO] Opening http://127.0.0.1:46661

Search for SocketAddr in rust std doc served on random port and open it in browser

$ cargo docs -bros SocketAddr
[INFO] Serving rust doc on http://127.0.0.1:40143
[INFO] Opening http://127.0.0.1:40143/std/?search=SocketAddr

Pro Tips

Passthrough cargo doc options after –

$ cargo docs -- --quiet
[INFO] Running cargo doc --quiet
[INFO] Serving crate doc on http://127.0.0.1:8080

If you are on WSL2, set BROWSER=/mnt/c/Path/To/Your/Browser.exe environment variable to open in desktop browser

$ export BROWSER="/mnt/c/Program Files/Firefox Nightly/firefox.exe"

Tired of typing -o, -ro, -row? Try these environment variables to save you some key strokes.

$ export CARGO_DOCS_OPEN=true
$ export CARGO_DOCS_WATCH=true
$ export CARGO_DOCS_RANDOM_PORT=true
