Warnalyzer

Remove unused code from multi-crate Rust projects.

The dead_code lint family of rustc is limited to one crate only and thus can't tell whether some public API is used inside a multi-crate project or not.

This tool, warnalyzer, provides unused code detection functionality for such multi-crate projects.

Usage (scip backend)

This backend supports stable, but it requires rust-analyzer to be available. Obtain it through rustup component add rust-analyzer.

Limitations

save-analysis backend

[!NOTE] The save-analysis backend depends on the nightly feature save-analysis which was removed in February 2023. In order to use warnalyzer, use a nightly Rust version before February 16, 2023. (Issue)
