cargo-machete

Remove unused Rust dependencies with this one weird trick!

build status matrix chat supported rustc stable

Introduction

cargo-machete is a Cargo tool that detects unused dependencies in Rust projects, in a fast (yet imprecise) way.

See also the blog post for a detailed writeup.

Installation

Install cargo-machete with cargo:

cargo install cargo-machete

Example

Run cargo-machete in a directory that contains one or more Rust projects (using Cargo for dependency management):

cd my-directory && cargo machete

alternatively



cargo machete /absolute/path/to/my/directory

cargo machete /absolute/path/to/my/directory

To ignore a certain set of dependencies in a crate, add package.metadata.cargo-machete to Cargo.toml, and specify an ignored array:

For example:

[dependencies]
prost = "0.10" # Used in code generated by build.rs output, which cargo-machete cannot check


[package.metadata.cargo-machete]
ignored = ["prost"]

[package.metadata.cargo-machete] ignored = ["prost"]

If there are too many false positives, consider using the --with-metadata CLI flag, which will call cargo metadata --all-features to find final dependency names, more accurate dependencies per build type, etc. ⚠ This may modify the Cargo.lock files in your projects.
