Crate cargo_shear 

cargo-shear

A tool for detecting and removing unused dependencies from Rust projects.

Overview

cargo-shear analyzes your Rust codebase to identify dependencies that are declared in Cargo.toml but never actually used in the code. It can automatically remove these unused dependencies with the --fix flag.

Architecture

The codebase is organized into several focused modules:

• cargo_toml_editor - Handles modifications to Cargo.toml files
• package_analyzer - Analyzes packages to find issues
• package_processor - Processes packages and detects unused dependencies
• source_parser - Parses Rust source to extract data

Usage

use cargo_shear::{CargoShear, CargoShearOptions};

let options = CargoShearOptions::new_for_test(
    std::path::PathBuf::from("."),
    false, // fix
);
let exit_code = CargoShear::new(std::io::stdout(), options).run();
