feature selector

All default features are marked Green.

When hovering above a feature it shows other features which the selected feature requires.

Features marked with 📦 mean that they require an optional dependency.

Features which an active feature requires are marked grey.

Features marked with 🗃️️ are enabled by the workspace dependency and can only be disabled by the workspace dependency

search mode

At any point you can start typing like normal. This will start using your input as a search query.

prune

You can run prune with cargo features prune

this will disable all features which are not required to compile.

false positives

Some features may not cause the compilation to fail but still remove functionality. To limit the extent of such cases we keep a file including all known false positives. These features will not be disabled by cargo features prune and instead be display gray letting you know that you should consider if you really need the feature.

If you know of any other features that fall under this category fell free to open an Issue or PR!

If your project requires additional features to be always kept. You can add a section to your Cargo.toml named cargo-features-manager.keep in there you can define which features will be kept.

# Cargo.toml

# for individial packages
[cargo-features-manager.keep]
clap = ["default"]
color-eyre = ["capture-spantrace", "track-caller"]

# for the whole workspace
[workspace.cargo-features-manager.keep]
clap = ["default"]
color-eyre = ["capture-spantrace", "track-caller"]
