cargo-all-features

A Cargo subcommand to build and test all feature flag combinations.

Install

cargo install cargo-all-features

Usage

Build crate with all feature flag combinations:

cargo build-all-features <CARGO BUILD FLAGS>

Test crate with all feature flag combinations:

cargo test-all-features <CARGO TEST FLAGS>

Why?

If you have a crate that utilizes Rust feature flags, it’s common to set up a test matrix in your continuous integration tooling to individually test all feature flags. This setup can be difficult to maintain and easy to forget to update as feature flags come and go. It’s also not exhaustive, as it’s possible enabling combinations of feature flags could result in a compilation error that should be fixed. This utility was built to address these concerns.
