Unfeature: Expand Known Rust Features

Removes all blocks that are disabled by features and the attributes of enabled features.

This tool can be used to create handouts for programming assignments.

Usage

This is a cargo tool, that can handle entire crates (including local workspace dependencies).

cargo unfeature <output_dir> <match_features> [additional_files...] [options]
Options:
  -F, --features <FEATURES>            Enabled features
      --no-default-features            Disable default features
      --all-features                   Enable all features
      --manifest-path <MANIFEST_PATH>  Path to Cargo.toml

This tool creates a copy of the crate in <output_dir> with the specified features being expanded.

It also removes disabled optional dependencies from the Cargo.toml manifest.
