README
cargo-udeps
Find unused dependencies in Cargo.toml.
While compilation of this tool also works on Rust stable, it needs Rust nightly to actually run.
Installation
GitHub Releases
https://github.com/est31/cargo-udeps/releases
cargo install (crates.io)
cargo install cargo-udeps --locked
cargo install (master)
cargo install --git https://github.com/est31/cargo-udeps --locked
Dedicated packages
Some package managers have packaged cargo-udeps:
- Nix/Nix OS:
cargo-udeps - Arch Linux:
pacman -S cargo-udeps - Homebrew:
brew install cargo-udeps
Usage
cargo +nightly udeps
It either prints out a "unused crates" line listing the crates, or it prints out a line saying that no crates were unused.
pre-commit
You can use it as pre-commit hook:
- repo: https://github.com/est31/cargo-udeps
rev: v0.1.47
hooks:
- id: udeps
Ignoring some of the dependencies
To ignore some of the dependencies, add package.metadata.cargo-udeps.ignore to Cargo.toml.
[package.metadata.cargo-udeps.ignore]
normal = ["if_chain"]
#development = []
#build = []
[dependencies]
if_chain = "1.0.0" # Used only in doc-tests, which `cargo-udeps` cannot check.
Alternatively, add dependencies to workspace.metadata.cargo-udeps.ignore in the
workpace Cargo.toml to ignore them in all packages in the workspace.
Known bugs
-
Some unused crates might not be detected. This includes crates used by std and its dependencies as well as crates that are already being used by dependencies of the studied crate.
-
Crates are currently only handled on a per name basis. Two crates with the same name but different versions would be a problem.
