Cargo Graphmod

A cargo subcommand for building Graphviz DOT files of dependency graphs between the modules of a package.

Prerequisites

• You need to install Graphviz.

Installing

cargo-graphmod can be installed with cargo install:

ignore cargo install cargo-graphmod

Usage

ignore cd my_rust_package cargo graphmod | tred | dot -Tsvg > modules.svg

• Use tred if you want the transitive reduction of the graph.
• You can export to a lot of different formats.

Known limitations

• Detects only dependencies introduced by the use keyword.
• Works best when there is a bijection between modules and files / directories.

License

cargo-graphmod is released under the terms of the GPLv3 license.
