cargo

name	cargo
description	Use when initializing Rust projects or modifying Cargo.toml, Cargo.lock, cargo config, or other cargo-related files. Prefer this skill for dependency changes, features, package metadata, workspaces, and cargo commands. Do not load it for editing Rust source code generally.

Cargo

Prefer cargo commands over manual edits to Cargo.toml, Cargo.lock, and other cargo-related files.

Workflow

1. Use cargo for project setup and manifest changes whenever possible.
2. If you need an operation not listed here, inspect cargo help or the relevant subcommand help, for example cargo help add or cargo help init.
3. Edit cargo-related files manually only after you fail to find a cargo command that achieves the needed outcome.

Examples

Initialize a new project:

cargo init
cargo init --lib
cargo new my-crate
cargo new my-crate --lib

Add dependencies:

cargo add serde
cargo add tokio --dev
cargo add anyhow --build

Enable dependency features:

cargo add serde --features derive
cargo add tokio --features rt-multi-thread,macros
cargo add reqwest --no-default-features --features json,rustls-tls

Remove a dependency:

cargo remove serde
